Hello aravindh,
The basic eligibilty criterion for pursuing the course is 10+2 or equivalent qulaification in the science stream ,from a recognized educational board ,with a minimum aggregate score of 50 percent .
Admission to the course is based on candidates performance in relevant entrance exam or merit obtained in the last qualifying exam.
So, you are not eligible for this course since your 12th is not finished .might be chances to be admission based on the entrance exam they conduct
Good luck
