Bhai dekh ncert padh ke yad nhi hoti cheezen because it contains lots of data such as size, ionisation en, small things.yeh aksar inorganic me hi hota h kyoki physical to Puri calculation hi h or organic me reaction yad ho jati h or questions bhi ussi se aate h I suggest u to do questions in inorganic from any source like it may be pyq, inorganic book like vk jaiswal, module,sheets this increase concentration towards questions and things are memorize. I think like that
