How should I begin preparing for CA foundation as a 1st PU student

Hello!

I’m currently a 1st PU commerce student and I’ve already decided to become a Chartered Accountant. I want to start preparing for the CA Foundation exam early, but I’m not sure where to begin.

Can anyone guide me on:

🔹 Which PU subjects are most useful for Foundation prep?

🔹 What topics should I focus on in Accounts or Law at this stage?

🔹 Are there any good free YouTube channels or beginner notes?

I’m hoping to use this time to build strong basics. Thank you so much in advance!
