CBSE 12th

As per your question I can say that still you have chance to get good percentile but that requires hard work from your side. If you are from any coaching institute then I recommend you to blindly follow their materials. First five days that is from Monday to friday study inter 2nd year portion and Saturday, Sunday go through inter 1st year portion as many chapters from 2nd year has connection with 1st year chapters. Study at least 12hrs day, giving each subject 4hrs in which 1hr30min for theory and 2hr30min for practise. No matter what if you like the subject or not you have treat three subjects equally. Work hard with discipline and dedication you are going to make it.
