Analysis of MCS 24 December 2019 Question Paper

 MCS 24 question paper of December 2019 has asked the students to write ten programs overall and that too seven Java programs were asked to be written in the first question which is compulsory. So for the students who are thorough in programming, the paper is moderate to easy and also scoring one. For students who are not that good in Java programming, MCS 24 question paper will be a little bit tough and due to the inability to write Java programs, they would lose out more than half of the marks.

So overall the IGNOU MCS 24 December 2019 question paper was moderate for scoring.
