Hello,

It would be much better if you could mention which exam you are talking about.

Also after every exam the coaching centres find out the answers and also find out the wrong questions which could be given as bonus.

So you can check in the website of various coaching centres.

Also the exam conducting body declares the answer key,so you can find out from there.

If can not figure out then I would suggest you to wait till the result comes.

All the Best
