Hello,

Books of the most popular publishers are unfortunately only available in English. Considering that you feel that English will be tough for you, I'll suggest you to try English books and get over your fear. The questions and descriptions are usually written in a very simple manner, to make it easy for students to understand. You can try Arihant publication's book. They're always written in easy language. If you need Bengali books, you may refer to class 11 and 12 books of your board for concepts and use books of Santra publications. All the best!
