CAT

I will suggest you to put 2-3 hours daily and 7-8 or more hours whenever you get off . You can read while travelling like ET news on the app. And before you go office/college you can spend 11.5 hours as per your schedule working on problem and also after you come from office/college for 1 hours.
2. Now coming to your medium and strong areas just go through the basics once and daily solve like 5-10 problems from them to keep in touch till D- day comes.
3. Also read the newspaper editorial daily. Read the subject you are not really comfortable with.You can refer Hindu editorial and read articles at www.aldaily.com
4.Also as far as classes is concerned I will suggest you to look for Handa ka Funda.The tips and techniques are really useful .You would like to go through the link -Online Coaching for CAT and Banking Exams. Also GK course of Handa ka Funda will help you prepare for exam apart from CAT like XAT ,SNAP,IIFT,TISS.You can get tips and tricks needed for mocks from the course.You can get reviews about course here-What is your review of Handa Ka Funda?. But if you have joined the TIME or any other institute you can go ahead with it .
5. As far as mocks are concerned I would suggest you join CL Mocks as they are at par with CAT and AIMCATS,SIMCATS are generally way above CAT level.
6.Analyse the mocks which is more important than giving a mock .Do not attempt another mock without analysis one mock .Start taking mocks from the month of July last week .It could be too early but with few months to for CAT you have to buckle up.
7. 1 months before actual CAT give 2 mocks per week and here again analyse the mock.
8. Just an week before actual CAT exam ,stop attempting CAT mock test .Try to solve past CAT exam paper with 7080% accuracy.
