I am a student who missed +2 science so i can join the entrunce?
Hey !
All the entrance exams for engineering ask for a 10+2 passed or equivalent degree with Physics , maths , chemistry/biology/biotechnology as main subjects.
So , if you haven't passed 10+2 with science , you can not apply for engineering entrance exams like IIT.
Since different entramce exams have different eligibiluty criteria , i request you to mention the name of concerned entrance exam in comments.
May be the entrance exam you want to ask about , doesn't need 10+2 with science.
Best wishes!
