Hello Nikunj,
I feel sorry that you failed your class 12 but you should have opted for science only if you were really interested in this field because you can only become successful if you really have a passion for the field.
According to me, you should focus on passing your class 12 as colleges do not take in students who have failed HSC exams. Almost all the colleges require students to have minimum 50% marks in class 12.
So you should take this year and work hard to complete your 12th std with a good percentage so that you can go ahead in the field you wish to pursue.
Hope this helps.
