Guys any advice to absolutely demolish the methods exam next year?
Also, is it possible to get 100% on the exam? lol, i may or may not be aiming to do that 
With whether it's possible, it is because apart from last year, most people (depending year to year, sometimes everyone) that got a 50 study score full-marked both exams (considering I had a friend with really good SACS in strong school, and lost one mark across both exams and got a 49). So it happens every year, it's just very hard (especially in exam 2) to do so but not impossible.
I've done quite a lot of exams and never full-marked exam 2, although exam 1 is very easy to get 100%.
Just do many practice exams I guess, because practice makes perfect. That generally works for most people, even though I have a friend who did NOT do ANY practice exams any still managed a 49 (same friend as before, he did tons of challenging questions).
