My uni does only multiple choice exams. In my opinion it's the most horrible way of testing someones knowledge.
For example this stupid question right here:

Enzyme Kinetics, which statement is correct:
A: Vmax of a reaction is independant of temperature (correct but also incorrect to some extent, you can break the enzyme with a too high temperature but an enzymes theoretical Vmax doesnt change with temp)
B: Michael-Menten Constant : Km, says at which concentration Vmax is attained (wrong, it's for vmax/2
C: The lower Km the lower the affinity (wrong, the higher the affinity would be correct)
D: Enzymaticall catalized reactions are reversible (sometimes???)
E: Enzymes catalyze reactions by increasing the necessary energy to reach the transition state. (wrong, it's the opposite, they lower the energy to reach transition state - activation energy is lowered)

So to me A and D here both got a point but are not entirely correct, what would've been correct?
I failed this test btw - it was 26 questions like this and a portion of yes/no questions in 50minutes.
