# ISC Physics Syllabus

After 10th it is very difficult to take decision for students and parents to select the stream which is best fit for them. Whatever it is very common to observe that guardians/relatives have the tendency to admit their childrens into the scince stream for higher desire. Then after selecting the science stream they have to choose the board. ICSE/ISC is the one of best Board to follow the almost perfect curriculum like CBSE.So now students have to face the one of the most hardcore subject – ‘PHYSICS’. In this blog we are going to discuss about the detailed syllebus of class 11 ISC.

There are two papers in Physics class 11 for ISC. One of them is based on theory and another one is based on Practical.Details are mentioned below:

Paper I (Theory) : This paper contains 70 marks for 3 hours of written exam duration.

Paper II ( Practical) : This paper consists of 30 marks. The number divisions are subdivisioned as below –

• Practical (written) – 15 marks
• Practical File(Manual) – 5 marks
• Project work – 10 marks
