What is the difference between numerical value based question and non-MCQs?
S
sinbad chongtham

Numerical value based questions and Non-MCQs are similar in a way as there will be no options provided. The main difference is that Numerical value based questions are answered with the exact numerical value while Non-MCQs require an explation as well.
