Are multiple choce questions papers really hard to score?

Question

I wind up scoring C and C+ for my 2 exam papers that tested heavily on multiple choice questions. One is principle of genetics(core module) and the other astronomy(elective module). I thought that multiple choice questions were supposed to be easy, why did it turn out that the papers that tested less or none on MCQ were my results better?

Principle of genetics had 70 marks worth on MCQ in which more then 1 answer is correct while Astronomy, the entire paper was MCQ with only 1 answer correct. Why did the results turn out so bad even though I had studied them?

Answer 1

See multiple choice usually test ur IQ in it.

So maybe u might be good at genetics but not this much good at astronomy.
