Hello,
Jainism does not follow or believe in Caste System. Anyone who believes in principle of Jainism can Follow it.
Jainism is considered as a minority group in India but they are not entitled with reservation. Therefore, their cutoff is same as a General category student for any entrance exam.
However, if you belong to a tribal jain community with proper documentation certification you can opt for reservation.
Hope this was helpful.
