Hi Ankit,
Chandradhari Mithila Mahavidyalaya (CM College), is one of the reputed colleges in Bihar. The minimum eligibility to apply is passing in 10th. Usually the admission is done on the basis of merit and the marks obtained by the students. Si don't worry about selection. Just apply and wait for the merit list. Also keep some backup college application ready in case you don't make the cut here.
Good luck
