If you're a PCB student preparing for the GAT exam, you should primarily focus on NCERT books, as most questions are directly or indirectly based on NCERT concepts. NCERT helps build clear fundamentals and is usually sufficient for understanding core topics.
Once your basics are strong, you can refer to your state board books only for additional clarity or practice, not as the main source. Overloading with too many books can increase confusion.
