Yeah, it’s totally possible. I actually started my CAT prep just two months before the exam and still managed to get a good percentile and calls from top colleges. I had to grind pretty hard, especially for the interviews after CAT, but it worked out. If you put in focused effort and really practice, you can definitely pull it off. That said, the earlier you start, the less stressful it is and the better your chances. So if you have the time, don’t wait. But if you’re starting late, don’t get discouraged; just go all in.
