OCR 21st Century

Each exam board is different and you need revision notes tailored to your needs. I've spent a lot of time going over the exams and I think I know what the examiners think is important, what the mark-schemes are, the techniques that will help you improve your grade.


All of the e-books you'll need can be found here.

These include Maths and Calculator Skills for Science Students covering all those tiny bits that A* students are expected to know but are really more maths then science.   

Maths (The Chemistry Bits) for GCSE Science, available in higher and foundation versions and covering all the mathsy topics you'll need for your GCSE, with answers at the back. The foundation version is aimed at C grade students, in the higher version each section starts with simple questions that B grade students should be able to cope with, and ends with questions that will challenge A* students. 

Maths (The Chemistry Bits) for Triple Science is also available (higher and foundation) and has three extra sections needed for triple science.


Scroll down to either Chemistry or Physics and you'll find links to the page on here with all the details and to the YouTube Playlist.

How The Course Works

It can be confusing with all the codes to know which videos you need to be watching. First you need to know if you're doing core, additional or triple (separate) science.

 Science A C1, C2, C3 P1, P2, P3 B1, B2, B3
Additional Science A C4, C5, C6 P4, P5, P6 B4, B5, B6
C7 P7 B7
Chemistry GCSE Physics GCSE  Biology GCSE


These are the exam codes (yes, triple science students are sitting 9 exams, and doing 3 CA's!) this is the first part of the codes below. Each exam is worth 25% the CA is the other 25%. I have a large collection of videos to help with your preparation.
