Sir! I am studying BBA. I am self preparing.i am free at early mng hours n evening hours .how should I plan my timetable for preparing cat

If you want to appear for CAT next year you should atleast study 3-4 hours daily. You can study in morning or evening as per your choice but make sure you cover the basics of all the sections by June 2018.

In June, When you are sufficiently confident with these go for Mocks and try to give your best. But even at that time thoroughly analyse your performance and identify your strengths and weaknesses and make a strategy accordingly.

In the last three months devote atleast six hours daily for the final revision and the mocks.

All the best!
