The whole idea of delivering these online lecture is to
-Provide a free facility to those students who might not have resources to engage with well known Expensive Physics Teacher
-Place a Conceptual Teaching Trend in Pakistan.

These lectures can also be delivered to those students who doesn’t have internet facility (in Pakistan), if you know any of these students let us know, we will deliver them by ourselves.

Hope you enjoy doing Physics while watching these lectures.
