Hello Aspirant,

With score of 42 marks in COMEDK you cannot get any good college but yes you can get college which will not worth and if you belongs to any reservation category then you can try for some average colleges but in Bangalore it is quite difficult. You can refer to the link given below to get the details of last year cut-offs for COMEDK to have an idea :-

You can also use COMEDK College predictor to predict the colleges based on your COMEDK score :-

Now as we come to JEE-Main, so same thing with JEE-Main too, according to the percentile you have mentioned in the question your approximate rank would be near about 3.9 Lacs and on the basis of this rank it is not possible to get any good college even with any of the reservation category.

There are some low tier colleges which takes admission on low ranks too but with general category it is quite hard although I would recommend you to use JEE-Main College Predictor to predict the college according to your percentile and category :-

I hope this information helps you.

Good Luck!!
