Hey Rahat, 

JMI is a central university that provides courses like BSc, B.Tech, BE, Diploma, MSc, M.Tech and various other subjects like this. It does not provide any course for 9th class or upto 10th class. If you want to study in this university then you have to clear your 10+2 or 12th class with minimum 50% of mark. Then there are various courses in which you can study. The selection is mainly based on the merit list which will be made by the university. 

For your information I am providing the courses in which you can take admission after your 12th.

B.Tech

BE

B.Arch

BSc

BA

BBA

B.Com

BA-LLB & various other courses.

So 1st of all you have to study hard so that you can get a good mark for which you will not be out of the merit list to get admission.

Hope you have got your answer, if you need more help then feel free to ask. Thank you
