Hello Shrishail!

I understand your concern over the medium of instruction in 1st PU. It is very difficult to shift from Kannada to English medium of instruction suddenly. However, it is not impossible. All you need to do is to put more efforts.

Firstly, many colleges in Karnataka do explain the subjects in Kannada as well as they are well aware that there are students from different backgrounds. So you can always approach your lectueres if you find any difficulty.

Secondly, the language in textbooks is not really very tough english. So practice more. Try to understand the topic in Kannada once you read in English. It may take time. Practice by writing also as this improves your understanding even better.

There are several videos available in youtube in kannada which explains concepts well in case you dont understand. Reach out to your friends without hesitation.

You will definitely learn it soon. All the best!
