Going to start following this thread, looks great and I do math too ( math bio chem y13 )

Trig identities are a pain but you get it eventually.

Well done for getting that essay done, a running joke in my house is that essays only take as much time as you have to do them!

DO NOT touch Khan Academy - it's not suitable for the UK.
What's wrong with it? Never knew, tons of teachers speak well of it at my school, or maybe I've misinterpreted their sarcasm? :confused:

It uses US terminology - so, for example, their 'trapezium' isn't the same as ours.

Back after a 5 mile running cup. Applied to my first internship a few days ago (and got rejected, such is life) but taking it in the stride and still pressing forwards, not expecting to get one - i'm 16 and competing against uni students. Studying for a few a level mocks and running a cs club tonight where i'll be taking a few kids through a box (cybersecurity pentesting) and see how it goes

screwed my halfterms oh well

spent like 30hours revising for my maths and ended up getting a 14/41, still feel a bit bitter about that but working on it (pretty sure it was just accuracy rather than problem solving that was the issue)

So as part of my a level homework I just proved the cosine rule exists. After (I kid you not) spending 5 hours on the one simple question.

I feel so proud of myself for solving it but also feel like a total rxtard for spending five hours on it.
