Many have to learn some new materials/chapters. Some institutes have completed the full syllabus.
If you have not yet completed full syllabus, you have to learn daily some new materials by sitting in the class, studying at home and doing problems in these chapters.
Revision: Have a plan to complete one full revision of all chapters by December end.
Mastering chapters: Have a plan to master at least one chapter for day. I earliest said five point revision per hour. Do five point revision for the chapter you want to master on a day.
