Set your daily routine and keep a fixed time for studying for your entrance exam. You must allot specific number of sufficient hours for your self study, apart from those you devote in school/coaching classes. Self study is a must and can't be deleted from the algorithm. Assign a few hours for recapitulating whatever you studied in the entire day. It is important that you revise you daily studies and make necessary notes. t the start of the course, students often feel that they have ample amount of time and they can read more than what the syllabus holds, for it will ensure a better security for them. The general notion being: the more you study, the more you score. This is true but given that you stick to the syllabus. Find out your strengths and weaknesses once you are well into the syllabus and keep referring to the syllabus occasionally so as to remain on the right track.While preparing, write down the important concepts that you might need to come back to, no matter how difficult the topic is. Once the preparation of that topic is done, refer to these notes that you've prepared to strengthen your roots.
