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.
