Hey!

So first of all, considering your tag for 'College of engineering, Trivandrum' , you cannot take admission in this college with WBJEE exam score. You need to appear for KEAM (KERELA ENGINEERING ARCHITECTURE AND MEDICAL EXAM ) . However, WBJEE is conducted by West Bengal joint entrance exam board which allows students to take admission in engineering colleges in west bengal .

Your rank in WBJEE is 60000 which is not a very good rank to get CSE in good college. You'll need to go for management quota in some private college and take admission by paying high amount of fees which can be ~10+ Lakhs which is not preferrable anyways. Either you should prepare for other engineering exams like JEE MAINS session 2 or you can also take a drop year and prepare well and finally score good to get a good government college
