JEE Main

With 50000 as your rank and having OBC category, you will surely get options for many NITs. You can choose the college and branch when you get exact rank. All the best.

Chance are less, but it all depends on your OBC - PWD rank. You may get some new NIT with non-core branch. All the best.

Since there is no official release of the result and hence the cut-off is not mentioned, I will not be able to give the range of your rank. But you can choose the Shiksha rank predictor. These might help you in getting the rank related query.

The best colleges are IIT, IIIT or NIT. Basically, many colleges accept JEE Mains score like Delhi Technical University, DAIICT-Delhi, etc. These are the best colleges which you can have better career options. But hope for the best so that you can qualify with impressive marks and get a seat in these colleges.

May I know your category?

Hello Sachin,
Till offline as well as online exams are not over one cannot hope to get an official version of correct answers. Though unofficial versions are already flooding the market, nobody can guarantee correctness! So I suppose waiting for the online exam to be over is the only safe option.

It can only be told when the result of JEE Mains will get announced. The cutoff depends upon the number of candidates appeared, higher marks achieved in the exam.

If you belong to general category you should check the best possible private colleges that you can get. Some of those colleges are Manipal, BITS, SRM, VIT, etc.

It depends upon the cutoff which has not released since the result is not announced. The result will be coming on 30th April 2018. After this the cutoff for the different categories will be announced. Then if you do not attain the minimum score then you will not get any college but if you have qualified with above minimum marks then it might be possible that you will get the college.
