Hi Rajeshwari,

If you have not yet completed class 12th then you should do so immediately.

Well if you study only the required chapters very easily then you will pass quickly.

The question papers are holistic but some chapters have more questions that the other carrying heavy marks. If you try to focus on those questions and then answer them then you might clear class 12th. Same strategy can be used for all the subjects.

I hope this information helps.

All the best.
