GUIDE ME GUYS

Focus on building strong fundamentals instead of rushing into mocks.
Develop a daily reading habit for VARC.
Strengthen your basics in Quants and solve a few DILR sets regularly.
Even 1–2 hours of consistent study each day will put you in a strong position by the time you appear for CAT.
Also, maintain a good CGPA and participate in extracurricular activities, as your academic profile and overall profile matter during MBA admissions. Stay consistent, avoid resource overload, and enjoy your college life alongside your preparation.

If you are someone who is not at all interested in cse then i would suggest you to start right now
But if you like coding you can explore into cse itself and then after gaining skills you should decide whether to do CAT preparation

I recently completed my CS engineering

I regret wasting my initial days doing nothing its good to see that atleast you are aware
