hi shuchita, NEET is an exam exclusively for doing MBBS in india alone, in case you are looking forward to do your PG abroad (which is better after doing mbbs here) i would suggest you how u could do it

USA- clear all the 3 steps of USMLE , attend interview and get your residency in you desired field

UK- u need to clear PLAB atep 1 and step 2 and then work there to do your PG

australia-clear AMC but mind it, it has many disadvantages

NZ-if you clear usmle u r eligible for new zealand as well, you just need to clear NZREX which is a clinical exam. good luck
