Hello Pranay,

You can take admission in a college based on either NATA exam 1 or NATA exam 2. NATA exam 2 results take less time to come out as compared to NATA exam 1 they are released within 10 days of the exam so that the counseling process can start. After the counseling process is started the classes get started in the first week of august for both NATA exam 1 candidates and NATA exam 2 candidates. There are different seats for both exam 1 and exam 2 candidates. You can give both the exams and choose the exam from which you want to enter the counseling. 

All The Best.
