Yeah, you can get admission in many private colleges.
You have chance to join central india's top private institutes medicaps and svits as this year 3 new branches are enrolled in this year .
B.tech in cloud computing
B.tech in data science
B.tech in artificial intelligence.

Sorry to say but you didn't scored enough to get admission in any NIT or any government college through jee main and even if you manage to get admission in any college i fear you have to compromise in your choice of subject as you might not be able to get the core branches . So I would suggest you to rather prepare for any other engineering entrance exam or to look for any good private college and side by side you can attend the jee main counselling and try your luck . Many private colleges give admission through merit list in which your 12th standard aggregate and jee main marks are considered whereas some college give admission through the results of their own entrance exam
