Another useful documentary on the Mandelbrot set:

This is a fascinating area of maths... to learn more, you can look up some of the key terms (fractals, chaos, strange attractors) online. It may keep you entertained for years 
When I was a student at Monash I had the privilege of doing a vacation project in this area, at Sydney Uni with Mike Field, who is one of the authors of this book:

That was an awesome doco, but I do wish they'd delve into more of how it relates to complex numbers and stuff, there was a scene where they just scrolled over the psychedelic M-set for like 2 minutes straight with trippy music hahaha
@AspiringDoc, it's pretty much all practice for quadratics, linear and trig. For instance, the more you'll practice, the quicker you'll be able to find delta of a quadratic, x and y-intercepts of linear graphs and trig exact values. If you do it enough, you'll be able to do it in your head, saving precious time.
Another thing I'm guilty of is being perfectionist with my handwriting, but after I ditched that on maths exams, my speed went up quite a bit.
