F.Sc (1st Year) Physics Solved Pdf Notes

The students of F.Sc first year (class xi) pre engineering & medical both read the physics book in their 2-year duration which has been published by punjab textbook board lahore. This book is used in all other boards of punjab (i.e. bise Lahore, Multan, Sargodha, Bahawalpur, Sahiwal, Gujranwala, Faisalabad, Rawalpindi, DG Khan, Federal boards etc). Physics is an important subject for hssc-i or inter f.sc ics (part 1) students. The students of medical and non-medical both read the book of chemistry as their course. Moreover, it has eleven chapters. you can download the Solution (Notes) in pdf form to your mobile and also read online on our website.
