BSc 1st Year Physics Syllabus 2023 is Revised in 2075 as Bachelors Course is Upgraded into 4 Years from 3 Years in the Name of Practical Education. We aren’t Talking about whether it was a good Move or a Bad Move as a lot of bachelor’s Colleges are about to shut down their business due to the lack of Students; today we will understand the newest syllabus of BSc Physics.
Overview of BSc 1st Year Physics
If You Have Passed +2 in Science then you will be eligible to study Bachelor of Science(BSc). There are two groups in the Science Stream:
- Physical
- Biological
The Physical group can go into Physical subjects and the Biological group can go towards Biology Subjects & Physics is the Major Subject of BSc 1st Year Physical Group Students.
