Hello Mansi according to me you should take a gap only if you are confident enough that you will surely score well in CAT and get a good college, and one more thing is that if you have not given any entrance exam this year then you have to wait for CAT/XAT/CET/SNAP etc.because entrance is compulsory to get admission in a MBA college.

Your question is not clear. If you want to pursue online MBA than aspirants need a graduate degree in any discipline to pursue Online MBA programs.
Although CAT, XAT, GMAT and other management test scores are not required, seats are offered after some form of candidate scrutiny, and at the discretion of the institute.
