stupid mistakes especially, mistakes, answering, like

Nishant1

On how many occasions have you made careless mistakes on "Least likely" and "most likely" questions? On average, i've missed out on around 3 questions/exam because of this. I now highlight the wording before answering to cut down on careless mistakes.

Even though it doesn't seem like a lot, it definite does add up, especially if you're in the mid 60's to 70's range.
