Hello Aspirant,

By the term general rank I do not know whether you are saying it is your AIR or it is your general category rank . So assuming that you belong to general category your NIMCET  rank is not enough for NITs. Based on the expected closing ranks the only possibilities are NIT, Agartala  -662 and NIT, Raipur -639 but still as you can see your rank is over 700 so thee is only a low chance. You can give it a try , because sometimes last minute vacancies may show up based on the number of seats and number of applicants .

You may refer the below list to see other MCA colleges accepting NIMCET and try in those , with your rank you have a good option:
