Classroom

You can go for self preparation. Along with that, you must join a good test series. Regular tests will help you evaluate your performance and work on the weaker topics. Just keep working hard and be determined. Keep notes of important formulas and short cuts.

If you are good at self-studying, then you can opt for DLP. But if you aren't, then regular classroom is the best way to keep yourself updated.

Please specify the course for which you are asking the question.
