The Method That Got You Here Will Not Get You There
In Class 11, the job is acquisition. You are meeting the sodium-potassium pump for the first time, seeing Newton's laws applied to pulleys, learning what a p-block element actually is. Reading a chapter twice, making neat notes, solving the back exercises, that sequence works because the brain needs repeated exposure to new material before it can hold it. The NCERT-first approach is correct at that stage. Chanakya wrote in the Arthashastra that knowledge must first be gathered before it can be applied, and Class 11 is entirely the gathering phase.
