I'm going to run a little experiment for a while. Every Tuesday until the exams, I'm going to put out a ten-question quiz on one of the A-level modules. I'd love to have feedback on whether you find them useful, how I can make them better, and what else I ought to cover! Here's the first one - it's on Core 2.

Core 2 basic facts quiz

This quiz takes you through some of the most important rules and identities for C2. Mastering this stuff won't guarantee you a good grade in your exam, but it'll give you a great foundation to work from.
(It's designed for OCR, but works just as well for the other boards).

Hi. Thank’s for the quiz, it’s really helpful.

However on question 10,

“If you know two sides of a triangle and the angle between them, which rule do you use?”,

you don’t say whether we are finding an angle or a side. [Spoilers redacted — CB]

## Colin

You’re quite right — I’ve now corrected the question. Thanks!

## AH

Hahahahahhahahaha Rule 34. Nice.

## Colin

Ha! I’d forgotten about that 🙂
