JEE Main Scores

At least 250 and more marks are required in JEE Mains exam to get admission in top IITs.

Don't go on a 'wild goose chase'. Some states have accepted JEE Mains as the eligibility criteria for admissions in colleges controlled by them and some states have not. Almost, every state has a domicile criteria too. Your best chance is either JEE Mains or if your state conducts its own CET, then scoring well in the concerned CET.

To get admission in an engineering college in Gujarat, of course, other than IIT/NIT, you have to appear for the common entrance test conducted by the Government of Gujarat, so marks scored in JEE Mains or class 12th board of Gujarat has no relevance.
