There are a few important notes you should be aware of:
- This book follows the AQA A Level curriculum set in the United Kingdom
- There is no IB-approved computer science textbook which covers the new exam (2014)
- This textbook has an excellent treatment of computer science
- ...but it covers material we don't cover in class
- ...and it does not cover material we do cover in our class
- I like the visual layout of this book, and the online support tools are excellent.
