Only certain chapters are appointed independent marks distribution for eg current electricity of 7 mrks.....

Namami Shukla 7 years, 6 months ago

Firstly cbse has given marks distribution unit wise and not chapter wise so they'll ask questions according to that only you cant predict that total _ mrks question will come from a particular chapter for eg acc. to cbse blueprint marks distribution for unit electrostatic is 8 so you cant claim cbse if they'll give all 8 mrks question from electric charges or all 8 mrks from capacitors........
