Ch#3–Download Free Notes Class 11th/FSC-I/ICS Mathematics (FBISE Islamabad) and Other Boards in shape of Video Lectures in Urdu Language

Dear Students,

Today, almost 90% of our students have joined different Academies for learning purpose. Some of them hired tutors and are charging high fee. We realize the factor and are very well aware that it is very much difficult for the parents to afford the high fee of different Academies / Tutors. We also concluded that the Academies are not providing good teaching services to the students but charging high fee from students. After realizing the factors we have uploaded the videos prepared by SABAQ foundation on our website which will really beneficial for the students as well as the people who are serving as teachers of different subjects in different institutions.

From this section you can download / view Video Lectures on Mathematics Class 11th / F.Sc / ICS Part-I for free. These Videos for F.Sc students have been prepared by SABAK Foundation for the ease of students as per new and updated syllabus/course prescribed by Federal Board of Intermediate & Secondary Education (FBISE), Islamabad – Pakistan and other BISE(s)/Boards of Pakistan. We are fully hopeful that after after watching/viewing these Video Lectures you will score 90% plus marks in your exams as they have been prepared in a very simple, easy, brief and in simple and lucid language to understand. The purpose of sharing these videos is to promote education in Pakistan and to help those students who really want to learn something. These videos are enough for learning purpose, and after watching these video lectures you will come to know that you are no more in need of any kind of tuition or Academy.
