Hi Aspirant,

You still have a LOT of time left for that.

You are eligible for CAT in your final year of graduation and after passing out.

Currently,you don't have much to do.

However,if you really want to start anything now,develop the habit of reading.

Also,focus on your percentage now.

When the time comes (maybe in your 2nd year of graduation),start solving questions of aptitude,logical Reasoning and Data Interpretation.Also,keep yourself updated with the economic world and it will help you in subtle ways.

Continue your good work.

Hope this helps.
