Hello ,

There is no chemistry and phyisics in Cs engineering but some maths and phy you learn in 11 / 12 will be useful for your higher studies in Cs engineering

The topics in physics that would be useful in CS / EEE / ECE  higher studies

• Work, Energy & Power.
• Properties of Bulk Matter.
• Waves
• Oscillations
• Electrostatics
• Current Electricity
• Magnetic Effect of Current & Magnetism
• Alternating Current
• Electromagnetic Waves
• Semiconductor Electronics: Materials, Devices and Simple Circuits

The topics in maths that would be useful in CS / EEE / ECE  higher studies

• Algebra
• Calculus
• Linear Programming
• Trigonometric Functions
• Principle of Mathematical Induction     (logical base for CS and Ec)

Hope this helps you

Best wishes for your future

Hello Aspirant

You will find subjects like chemistry, physics, maths even engineering drawing in the first year of your Btech computer science, though they aren't the main subjects of the course but in the first year they're important.
