It depends on your category. It is difficult to get Government College with these marks, if you belong to general category, but you can apply for some private universities too.

Minimum marks are basically called the cutoff marks, which is different for all category. Cutoff is high for the general category. Generally it is nearly 100, last year the cut off was very low comparatively previous years that is 81 for JEE main. For this year I can't tell you since the result is not release yet. It will be going to release on 30th April and the key will be released by 24th April. So, you are going to find your answer when the result will be released.

Hello Harshit,

All the best.

Assuming you belong to general category, you really don't have much options. You won't get anything out of JOSSA, so I would suggest you to explore your other options such as other entrance exams, such as BITSAT VITEE, SRM to get a seat in decent private college. All the best.

Which category do you belong from?

What is your JEE score tell me? If your JEE score is more than 100 you cant get good college because JEE SCORE is consider as MHTCET score. You have pay MHTCET fees for taking admissions in Maharashtra.

According to me, if cut-off goes high, you will be at boundary chance of passing and if cut-off goes low you will be qualified for JEE Advanced.
