It depends upon the JEE Main and JEE Advance cut offs, If You manage to qualify the exam by achieving the cut off, You can apply for JOSAA Counselling. It should be noted the cut off for EWS/SC/ST/FEMALES/OBC category is lower than the general category
However It is usually advised to fill the choices as per the preference of colleges and departments, for example CSE in NIT Trichy is your priority followed by CSE in NIT Warangal, you can fill CSE at NIT Trichy at serial number 1 and CSE at NIT Warangal at serial number 2 and so on and so forth. However to get any NIT, you must have qualified JEE Mains and to get any IIT, you must have qualifies JEE Advanced

But the previous cut offs of colleges should be taken in consideration, it is better to research over the cut off of colleges then make a preference list of colleges and fill accordingly

Hello Aspirant,

See on such SC rank you cannot get even any NIT so CSE in any NIT is definitely not possible on such rank because the closing SC ranks of last year were like :-

National Institute of Foundry & Forge Technology, Hatia, Ranchi - Metallurgy and Materials Engineering (13168)

Sant Longowal Institute of Engineering and Technology - Food Technology (13193)

Mizoram University, Aizawl - Electrical Engineering (130109)

You can check out previous year's cut-offs from the official website of JOSAA as given below :-

So on such rank and category you have no chance to get any of the NITs/IIITs/CFTIs/GFTIs THROUGH JOSAA counselling , so I would recommend you to either go for state counselling for autonomous government colleges or for private colleges or you can prepare for further attempts of JEE-Main and to help you in your preparation we have some resources which you can access from the link given below :-
