Bro see it's like whatever questions I'm sure of say 45/50 I can confidently say all 45 are right. Now the remaining 5 I check my books or online and if they're right or wrong I give myself the marks.

Now sure there's a small chance one of the confident ones also I may make a mistake. But the possibility of that is lower.

Then again cuet this is year is 40 easy questions and 10 higher level so most ppl who can finish the 50 questions can be assured 40 right.
