Used NEET NCERT PCB Books in Nagaland

So apparently I joined a coaching centre named Samarth coaching which is affiliated with Samarth coaching Rajasthan. I had to shift and stuffs so left the coaching centre and couldn't even read/use their books since I was given new modules from my new coaching centre. The books are all new, not even highlighted nor wrinkled. The modules comes with separate books each of class 11 & 12 containing enough mcqs for each chapter. Altogether there's 8 books for 11th std and 6 books for 12th std. Paid 10k for my coaching books but will be selling at half priced which is 5k
