Hello Sivanesan,
MCQ means Multiple Choice Questions.
Basically its a pattern of question paper where you have one question have 4 or more different options, from which only one answer is correct. So you need to select the right one.
Its simply like Kon Banega Crorepati questions.
Hope this helps, Thank You
All the best
