i have 52 percent in 12 so which courses can i get
Here you have not mentioned in which subjects you have passed 12th standard. You are planning for graduation, therefore, I must appreciate your gesture towards your career planning. For your graduation, you may choose any one out of many streams such as science (biology), science (non biology), arts, commerce, BBA (Bachelor of Business Administration), BBM (Bachelor of Business Management), BCA (Bachelor of Computer Application). You should choose subject of graduation, which is close to your heart and the subject/s you understand better.
The choice of subject for graduation will depend upon the subjects you have studied in your HSC. Now concerned to your marks in 12th standard, 52% marks are less for good institutions. But now a days there are many private colleges and institutes and universities, which offer many career oriented courses. You could try in such institutions, but you have to see the minimum marks required by the university.
