For clearing JEE Main and Advanced examination joining a good preparation course is not sufficient. This course will only pave the way for you to these exams and at the end, it's your task to walk on that path. The best thing is to make a schedule and study strictly according to that. If you do that, your chances to get these exams cleared will be multiplied exponentially.
