hi,

see if you want to join a tier 1 institute for mtech course, you need to appear in gate exam which is the national level entrance test, or you may appear in appgecet exam, vit mee, bits hd exam, iiit pge, srmjee pg, etc.

for mca courses you need to appear in nimcet, DUMCA, JNUEE, mahmca cet, BIT mca etc.

but based on your academic score you can not get any tier 1 and tier 2 colleges.
