Topics// what you have been studying these past two years, no? for last minute revision I'd focus on the topics you struggle with (everything, in my case)

Formula//
Area of a triangle= bxh divided by 2 & 1 half ab sin c
Cosine Rule, a2=b2+c2-2bccosA
Sine Rule, sin A over a equals sin B over b which is equal to sin C over c
Pythagoras, a2=b2+c2
Trig, SOH CAH TOA

Circumference of a circle, pi x diameter
Area of a circle, 2 x pi x r2

volume of a cuboid = l x w x h
v of prism = area of cross section x length
v of cylinder = pi r2 x h
v of a pyramid = 1/3 x area of base x h

parallelogram area= bxh
rectangle area= lxw
area of a trapezium= 1/2 a+b x h

quadratic formula = (-b plusminus the square root of b2-4ac) divided by 2xa
