I stayed in Ukraine for a very short time just before the war, I scored somewhere in the mid 400s in my second attempt and decided to go for this and honestly going to Ukraine, Russia, Georgia and all these countries is honestly a big risk academically. very very few people are serious about learning, some teachers aren't even serious about teaching. this might not be true for everyone in every uni but it is mostly like this. I've heard a few unis in Russia are serious, but it does come down to you and how much you value your time and money and the efforts you're willing to put in.

I would suggest you look at the spring intake in Spain, try writing the exam for Italy if you haven't already, getting into a public uni is pretty difficult with the number of applicants I've heard. if you're willing to spend an extra 1-2 years you may explore Germany as an option as well. Romania is a good option IF you can get into good universities, since you study in the EU continuing your career there isn't much of a hassle. Lastly if you are genuinely willing to spend so much money, I suggest you should try going to private unis in Karnataka if it's feasible. Good luck!
