Colleges in Karnataka

You can, but you will have to start from the BCA first year.

All Sundays and public holidays are considered to be off.

Christ University has two sessions of selection process. One in January and one in March. You can apply for the March process after you get your MAT scores.
You don't have to choose the specialization at the beginning itself. That will be after you complete two trimesters.

If you are going by ranks you can consider the following colleges apart from Christ.
1. Shri Ram College of Commerce, New Delhi.
2. Loyola College, Chennai.
3. Hansraj College, New Delhi.
4. St. Joseph's College of Commerce, Bangalore.

Study materials of all coaching institutions will be more or less similar. It depends upon how you study. However, according to my personal opinion, you should take Allen DLP course.

Hi there,
While you are preparing for CLAT, it's variable when marks are concerned, but you must aim for 160+ to get into top 50 i.e. for NLS, Bangalore.
However, it depends on the current year. However, going by past trends 160-170 marks shall make you stand amongst the top 50s.

It is practically impossible to do both of them simultaneously as you will need to pursue either 5-year LLB or 3-year LLB along with engineering which neither UGC allows nor its practicality.
