Hey.

Many people start pursuing courses like BA or any other Undegraduate course instead of dropping for preparation of CLAT. So if you clear CLAT this year then you can drop out of your BA college and take admission in the National Law university in the 5 year integrated course from 1st year. There will be no issue or problem in admission if you have already joined any undergraduate course. So you can prepare for CLAT side by side.

Best of luck
