WHICH REFERENCE BOOK TO CHOOSE?

I am from class 9 ICSE, if any bhaiya/didi can help me with choosing reference books, I'd be glad. There are many options in the market like oswal(book name:likely asked questions class 9), arihant, and together with. I want competency based questions to practice as our school is focusing on the same. Please help me 🙏🙏
