What should I do to increase my english marks?
Sure, that would be helpful.
You can try reading books like "To Kill a Mockingbird" or "The Catcher in the Rye" for high school level reading. Websites like Grammarly and EngVid.com have excellent grammar exercises and video lessons. For movies or TV shows, you can watch "Friends" or "The Office" as they are great for practicing conversational English.
