Candidates who have passed 10+2 with science and maths are eligible to apply for engineering entrance exams held each year by various engineering institutions across India. Many exams are at the national level while some are regional in nature. Some states have done away with engineering entrance exam or their own exam systems and have adopted JEE main and JEE advanced as the basis for admission. The major IITs across India conduct JEE for admission. JEE is quite tough and only a few pass this exam followed by an equally tough interview before gaining admission to IITs.
