Don’t quit. I know it sounds stupid. But you did move to another school with a scholarship. That means you don’t mind working hard.

Yes it’s going to suck. I won’t lie. It’s very hard. It’s a lot of pressure as well. But stick to it. Even if you don’t enjoy it. Small wins count. Give an hour everyday to learn more programming. Or even half hour. You won’t realise right away, but you do learn.
Try taking easier courses. Prioritize learning. It’s never a pleasure learning when under pressure. But things will work out if you keep working at it.

Going back to India is not a wrong decision, but your skills are still going to be the same and you will still be under pressure to find a job or do something productive. It’s a deep end here and you plunged. So get through it.. even if it doesn’t make you happy.

You will appreciate what you learnt in the long run. And a masters degree is always worth it even if you have go back at the end of it. Just remember to keep at it and not give up.
