That really is reassuring! It just seems so big and so strict!
Make sure you get a good partner (lots of group work.) They actually bring you in pretty slowly (there's a full prac on how to use a pipette.) By the end of it, you'll be running columns and purifying proteins.
Keep in mind that Amber is a (relatively) new coordinator, so exams and the like before 2013 aren't representative. She didn't put up any exams that she wrote last year. Her exams were harder then past exams, I found. The MST is really easy, just know how to do basic calculations.
Then you can do the third year subject, which is even more interesting

Haha noooo tms pracs are SUPER chill. And all the reports are done at home and the exam is only 35% so it's a really relaxed subject overall.
Just make sure that you're really, REALLY anal about using super clear wording when you write your formal reports because they take marks off for the silliest things.
Second this. My major complaint with the subject was they marked it to the rubric way to rigidly. They also didn't give partial marks, it was either 100%, 75% or 0% in each section (or something like that) - drop a comma somewhere, and lose disproportionate amount of marks. I prefer the way they mark the third year reports (much more holistic.)
That said, most of the 'reports' are just filling in boxes. Pass/fail, no problem here.
