Hey Ajay Sai,

In TS Board of Intermediate, except english and sanskrit/french/telugu/hindi subjects remaining Maths/Biology/Physics/ and chemistry are not out of 100 , this is for MPC/BIPC. You need to focus or practice a lost beca these are languages. In languages you can’t score easily because you need to write lots of theory answers without any spelling mistakes! 

when you consider for CEC/MEC all the subjects are for 100 Marks, because they don’t have any Practicals. You need to Focus on the concepts of the subjects instead of Byhearting.
