Hello Abhay,
There is no need to take a year's drop to solely prepare for the CAT exam as it takes around 6-months of diligent preparation to clear CAT. There are still some exams left like CMAT, CET and MAT through which you can get into some reputed B-Schools. However, if your aim is to get admitted into an IIM or a top non-IIM, then only I would advise to take a drop and prepare for CAT. Though you can give the aforementioned exams if you wish. All the best!
