Hey,
I wana know in case during the exam i am facing challenge to get the right answer or do not know the method at all. would it preferable to leave the question. Actually I am confused if the grading is affected by wrong answers or than the un attempted questions
No negative marking, if that’s what you meant. So answer all.
The test is a positive facing one, so there is no penalty for wrong answers, just no credit.
Conversely, there is no partial credit on answers either. If a MC requires (A), (B), and (D) and you only selected (A), you don’t get 33% of a point, you get 0.
Tl;dr, Study enough so that you don’t have to guess, but if you have to make a guess, try to make it an educated one because there is no disadvantage of guessing.
