Yesterday, CGP sent me an exam practice book for the new GCSE maths grading system (9-1) for free as a valued customer. I have never experienced any other company doing anything like this for their customers and I am extremely grateful of them for doing this!
CGP are hugely recommended by me to everyone!

Really pleased with the apps, they are very useful. Any idea as to when anymore may be released for Android (like A-Level ones)??

Chris — Bracknell, United Kingdom — 25 Oct 2016 at 15:10:07

Guestbook Editor: That's good to hear, thanks. Not sure when we'll be extending our range of Android Apps, but we'll keep you posted — it might even be exciting enough to justify a CGP tweet.

My children, 6 and 8, are home educated. We use your maths books, and have found them clear, helpful and fun. We have been using your books for 2 1/2 years and I've just placed another order. I am trying out an English one and some of the French books. They look great. Thank you for producing great material.

Guestbook Editor: You're welcome. Thank you for purchasing it.

very good for learning

I bought your cgp gcse aqa biology for the 9-1 course and the online edition was invalid. Otherwise your books are a treasure, goldmine and a good smacking joker book.

Arham — Harrow, United Kingdom — 22 Oct 2016 at 17:26:10

Guestbook Editor: We have no idea what a good smacking joker book is, but we'll take it as a compliment. Sorry to hear about your invalid Online Edition — I've passed your details to our Customer Services team, so they'll be in touch by email soon.

Thanks a lot, CGP!! You helped me get through my 11+ and now I'm studying in the school that I love. I will continue using CGP resources and definitely recommend it to my friends and family.

Verni — Woodford Green, United Kingdom — 21 Oct 2016 at 22:34:37

the jokes in your books made me wet myself in my own bed.

jeffrey — mossley, United Kingdom — 20 Oct 2016 at 10:35:18

Guestbook Editor: Better that than somebody else's bed, I always think.

There's a mistake in the A level chemistry revision guide (new spec) on page 8 in the table it says that the 3rd shell can hold a maximum of 16 electrons instead of 18, the working to get to an answer of 18 electrons is correct but the no. of electrons written isn't.

Your Name — Town, United Kingdom — 19 Oct 2016 at 19:43:44

Guestbook Editor: You're right — thanks for pointing it out. We'll correct this next time we reprint the book.

(Commenting on book MHN42, New Maths for GCSE and IGCSE® Textbook, Higher (for the Grade 9-1 Course)

Please check for the answer to question 10b section 9.4 equations problems. I make it 7.54. The answer at the back of book gives it as 8.54

Thank you.

Dilip parmar — London, United Kingdom — 19 Oct 2016 at 19:38:27

Guestbook Editor: Perhaps unwisely, I dusted off my equation-solving skills and had a go at this one myself... and my answer came out as 8.54.

But don't take my word for it — it's easy to check. The question tells you that h = 55x – 5x², so if you plug in your answer for x, you should end up with something very close to h = 105. Let's try it:

h = 55 × 8.54 – 5 × 8.54² = 105.042

So 8.54 looks like a good answer to 2 decimal places.

Wait! I think I can see what's happened. You've calculated the answer to part b using symmetry of motion and the info about the ball starting to fall after 5 seconds. It's *this* info that's wrong (it should be 5.5 seconds, but we simplified it because you don't actually need this if you're using recursive iteration). Sorry — we'll correct that.

Any idea as to when a level computer science guides will be released?

Shinichi — Manchester, United Kingdom — 18 Oct 2016 at 18:36:16

Guestbook Editor: No definite info on this at the moment, I'm afraid — but probably not for a while yet.

WOW!! These books are amazing! I have been using them for a few years now (where I first started with buying the sciences) and I always seem to end up coming back to this site to order more for my other subjects! They are so clear and easy to understand, and consolidate all the relevant information into a fun, useful format.

Lea — Warwick, United Kingdom — 17 Oct 2016 at 18:15:47

The books are brilliant. I am hoping I have chosen the correct ones. I wanted to know if there was a difference in content if the 'complete guide' for KS3 was any different to the individual books e.g. complete guide science versus individual bio, chem, phys

Chrissy — Park, United Kingdom — 15 Oct 2016 at 20:50:50

Guestbook Editor: Good question — there are some differences between our KS3 Science books. The Complete Study & Practice book contains the same succinct study notes as our Higher Level KS3 Science Study Guide (SHR32), but with several pages of practice questions added at the end of each section.

The separate Study & Question Books for KS3 Biology, Chemistry and Physics are a bit more in-depth, making them ideal for learning about Science in school and at home throughout KS3. Many of the notes are the similar to the Study Guides, but we've added in extra examples and info about the learning objectives, plus (different) practice questions and progress tick-boxes after every two or three pages.

All of these books cover the whole KS3 Science curriculum, so you won't miss any vital content by choosing one over another. It just depends how much practice you're looking for, and which style of learning you prefer.

for learning

tanjid — southall, United Kingdom — 15 Oct 2016 at 19:59:56

The GCSE Revision science and maths books were fantastic and helped my daughter get A* in Science & Maths. They were very clear and concise. I also liked the layout. The font size was large with lots of bullet points and concise paragraphs. Visually, this just makes it easier to find key information. Just bought the ALevel courses and the new GCSEs, I'm hoping they are just as good.

Dr Dow — London, United Kingdom — 14 Oct 2016 at 16:48:50

Thank you Helen for the excellent customer service. I forgot to add the answer booklet for one of the books I ordered and they were kind enough to send it to me without charging me again for postage. You rock CGP! :)

John Tan — London, United Kingdom — 14 Oct 2016 at 15:06:20

i used cpg maths books they were so so helpful thank you

Taylor — severn road, United Kingdom — 14 Oct 2016 at 14:03:24

I used CGP for my GCSE revision and I can quite safely say that, without the CGP books, I wouldn't have got such high grades, which in turn enabled me to obtain a place at college.

Rowan Richards — Ash Vale, United Kingdom — 14 Oct 2016 at 03:29:08

Guestbook Editor: Excellent — that's great to hear. Don't forget to mention us in your memoirs in fifty years' time.

I have been using the higher GCSE mathematics textbook for a while and it has really helped me to get to grips with some of the more complicated aspects of mathematics

Sam — Bristol, United Kingdom — 13 Oct 2016 at 16:47:30

when will a history A level guide be out?

Adan — algiers, Algeria — 12 Oct 2016 at 20:28:55

Guestbook Editor: Not in the foreseeable future, I'm afraid — we're not working on any A-Level History books at the moment.

I have been using your books for some time as a classroom teacher and find them so easy to use. This summer I move to Denver for two years with my four children and have just begun home schooling them, your books have made my job so much easier and the children enjoy the work and the exercises are fun and engaging. It is also very clear what they need to learn in each year. I also love the self evaluation at the end of each page as even my 5 year old twins understand this and it helps me to see who needs a bit more time on what topic. Thank you for creating such great easy to use products.

Katherine Page — Denver, United States of America — 12 Oct 2016 at 13:36:12

My students and I have loved the AQA CGP GCSE Business Revision Guide and workbook and I have bought truckloads in the last 4 years and the students have done well to God's glory. We are moving to the new 2017 Edexcel GCSE Business Spec and wondering when your fantastic revision guide and workbook will be ready?

Ang A — London, United Kingdom — 12 Oct 2016 at 10:00:28

Guestbook Editor: You and your students have excellent taste. We will be making a new GCSE Business Studies range in time for the start of the new courses — we're aiming to have the first batch of books ready by June 2017.

this is very helpful.

erin — GUILDFORD, United Kingdom — 09 Oct 2016 at 17:01:51

Easy to use website, quality revision materials, decent prices.

Anon — Milton Keynes, United Kingdom — 08 Oct 2016 at 14:46:08

My daughter has just brought home the KS2 English Reading Book1 and I am not impressed with the layout. The fold out pages make it very confusing to work out what questions go with what reading article. It took up our whole kitchen table opening out the folded pages - very impractical for an average home, impossible to use in school. Would be much better just on normal pages. My daughter got it free from school. I wouldn't buy it and won't recommend it to anyone.

Hazel Ross — LIVERPOOL, United Kingdom — 07 Oct 2016 at 18:20:39

Guestbook Editor: Sorry to hear you're not keen on the layout of our KS2 Reading SAT Busters. The idea behind the fold-out sections is to let pupils see the questions and the text at the same time (without having to keep turning pages to and fro), but we take your point about the width.

We're always thinking about ways to make our books as helpful as possible, and these SAT Busters are currently near the top of our list. So we'll definitely take your feedback on board — thanks!

its ok i guess

When will your new book for the new A level Edexcel Maths 2017 be released.

Danielle — Rudgwick, United Kingdom — 06 Oct 2016 at 10:46:12

Guestbook Editor: Hello — our new A-Level Maths range will be ready in time for the start of the new courses in September 2017. The first batch will probably start arriving sometime around June.

Hi, can you try to get other exams boards for a level business. Preferably edexcel

Leyton — Stratford, United Kingdom — 05 Oct 2016 at 21:32:57

I think the old cgp a level chemistry should not be sold next to the new ones cause it made my friend buy the wrong one

Rebecca — Minehead, United Kingdom — 04 Oct 2016 at 17:09:34

Guestbook Editor: Sorry to hear that — do you mean on our website, or another website, or in the shops? We've stopped listing the old A-Level Science books on our website, since the A2 courses ended this summer. (And before that, we labelled the old and new books with different coloured tags to make it clear which was which.)

Unfortunately, there's only so much we can do about how other shops and websites display our books. But if your friend drops us an email, we'll see if we can fix them up with the latest edition of the book.

I don't know what to think of mushy peas. Do I like them... Do I not? I think they're better with black pepper though.

drunken pigeon — loserville, United Kingdom — 03 Oct 2016 at 22:06:05

Guestbook Editor: You know, I think I'm struggling with the same question re: mushy peas. I like peas, but they're better non-mushy, it seems to me.

Good luck resolving your inner turmoil on this issue.

I just want to say, thanks very much for your wonderful revision guides for science! They helped me massively in achieving 3 A*s for Physics, Biology and Chemistry (which I was really struggling in)!

Anonymous — Leatherhead, United Kingdom — 03 Oct 2016 at 21:58:19

Guestbook Editor: Great news — glad we could help.

Is there any possibility CGP could create an A-Level Computing/Computer Science guide for September 2017?

Also, any chance of an EDEXCEL specific A-Level Economics guide?

L Lawliet — Birmingham, United Kingdom — 03 Oct 2016 at 21:14:16

Guestbook Editor: We can't make any promises about A-Level Computing at the moment... it's a subject we'd like to give the CGP treatment, but it's not on the cards just yet.

We probably won't be making an A-Level Economics book specifically for Edexcel, but our current Economics books cover AQA, OCR and Edexcel A — with notes on each page to tell you which topics you'll need to learn for each exam board.

I love your gcse books. please get rid of gcse title and put ks3 title on otherwise mom won't get it for me. I'm in y7 and I've got your ks3 books but I like your gcse ones more. please.

grace adeeko — Birmingham, United Kingdom — 02 Oct 2016 at 13:50:43

Guestbook Editor: We'd love to help, but what you're suggesting might be a little confusing for our other customers. Have you tried putting on a false moustache and a husky voice and telling your Mum you're actually sixteen? This almost always works, even if you're a girl.


I think there is a mistake in A2 Chemistry textbook for OCR A (new syllabus). On page 188, it says that etanoyl chloride will react with ammonia to produce ethanamide and hydrogen chloride, however, my chemistry teacher says that any HCl formed would immediatly react with excess ammonia to give ammonium chloride. So, the reaction should actually be: ethanoyl chloride + 2NH3 ---> ethanamide + NH4Cl

Anonymous — Nottingham, United Kingdom — 02 Oct 2016 at 13:37:49

Guestbook Editor: Hello — thanks for your comment. I'll hand you over to one of our Chemistry experts...

"The equation printed in this book is fine in the abstract world of theoretical chemistry — it shows a 1:1 reaction, which assumes all the ammonia has reacted with the ethanoyl chloride (as it would if there were only one molecule of each) and the reaction stops there.

"But in reality, there isn’t simply one molecule of each reactant... this means you will get some HCl product reacting with ammonia to produce ammonium salt.

"So you and your teacher are right about what happens in a 'real life' reaction, especially when the ammonia is in excess. Next time we reprint the book, we’ll add a tip next to this equation to clarify this. Thanks!"

Really good book my two twins actually have this book for homework. It really challenges them to do the best they can. My girls say it can be very fun.

I'm looking for help with drama a level ? Wjec board. You don't seem to cover drama ?
Btw, the ten minute sats tests for English and maths are great. Do you have anything to help with the reading test ?

Ally cutler — Stockport, United Kingdom — 27 Sep 2016 at 19:45:15

Guestbook Editor: Hello — we can't help you with A-Level Drama at the moment, unfortunately. But we do have plenty of brilliant books for the KS2 English SATS Reading Test, including three SAT Buster Workbooks and two books of 10-Minute Tests. You'll find them all on on our KS2 English SAT Buster page (about halfway down)!

Thank you so much for your great books. I managed to get 2 Cs and 7 Ds at GCSE. Do you write any books for level 2 Hairdressing ("Level 2 - Hairdressing Diploma, City & Guilds")?

Fred Ford — Croydon, United Kingdom — 24 Sep 2016 at 20:34:49

Guestbook Editor: You're welcome. But we haven't branched out into hairdressing or other C&G Diplomas yet, I'm afraid. Sorry!

Some of your website certificates seem to have expired (I got a notification about an invalid certificate when accessing the online edition section of the site)

Fred Ford — Croydon, United Kingdom — 24 Sep 2016 at 20:29:35

Guestbook Editor: Thanks for letting us know — these certificates have been renewed, but the warning messages are still coming up in some browsers. Our IT team is on the case, so it should be sorted soon.

Great books
