Hello,
For your parents to come to russia from india is a 21 hour flight usually costing around 85000/- per head.

Also the fmge passing rates for the previously conducted fmge exams is less than 25% and the indian  medical education is better in terms than that for medical institutions in russia/ukraine.

We suggest you to take a 1 year drop for thorough neet prepartion and get a good indian medical college in neet 2021.. A drop from neet preparation is an better option as 60% of medical stidents are droppers. also it really doesn't matter in long run.

You can use careers360 college predictor to know the colleges you can get at your NEET score;- https://medicine.careers360.com/neet-college-predictor?icn=QnA&ici=qna_answer

Hope this helps
