Greetings to all , this side I am Saad Abdullah Makhdoom from Pakistan. I have always been interested in science subject so did my higher studies taking Physics as my principle subject . I am here to get associated with students who are keen to learn Science and especially phyiscs in very experimental way.

The higher secondary stage is important and challenging stage of school education as it is a transition from general science to discipline-based curriculum. There is a need to provide the learners with sufficient conceptual background of Physics which would eventually make them competent to meet the challenges of academic and professional courses after the higher secondary stage. In this course we will cover all chapters with very interactive classes with the students.
