CBSE 12th

Your question carries insufficient information. Please clarify. Which state you studied for the last 5 years?

You should take graphics designing or animation courses.

Getting admission to DU is not possible as you are an NIOS student. Secondly, the cut-off for DU is also very high. In LPU, you might get admission since it is a private college. It is a very good college. I am not sure whether you will get admission to LPU since it also conducts its own entrance exam. If the eligibility criteria for the entrance exam is less than or equal to 55%, then you are eligible for giving exam. But remember in that case, you have to score good marks in that for getting admission in it. I will suggest you to check the eligibility criteria for the LPU entrance exam.

You can apply for SIMSREE.
For reference-
Cut-offs for 2017 were-

AI (CET, CMAT, CAT): 99.95
PGDBM

Sorry to say, it is not possible because there is an age limit to take admission in engineering colleges across India and for top colleges through JEE, you only have 3 chances (including the 12th passing year) to give JEE examination.

ELIGIBILITY:
Students who have successfully completed 12th Standard Examination (+2/ HSC, or equivalent level of examination ) from any recognised board can apply. Age: 17 to 24 years. 12th Pass.
If you abide by this eligibility criteria, then you can take admission in aviation course at Skywings Academy of Aviation and Tourism.

Hello Dipika

Check it and prepare for NEET exam and then go through the college in which you selected through your rank.

Yes, you can. Apply for some of the NGO's and try pursuing a short-term course in social work as that will help you the most.
