Hello Vatsal

You mean 50 percent score according to the paper.

Than your concepts must be strong and if you have done enough practice than only you can score.

Because within one month if you start from the beginning it is difficult; so it depends upon your previous practice.

All you can do is solve some good level questions ( master package of any good instuinst); theory ; and practice last year's exam with proper sitting.Refresh your concepts and study those concepts which you have skipped ( due to any reason).try this focus on silly mistakes and make habit not to do in next test .

And during exam don't be panic and try to be calm and relaxed and if you think that exam is very difficult than it will be for all ( accordingly cut off will decrease)

Good luck
