Hi aspirant...!

Hope you're doing great....!

So, with regard of you're query. basically, most of the part chemistry in 11th and 12th grades deals with organic and inorganic chemistry. when, it compared with physical chemistry. most of the questions come from these two parts in chemistry in  JEE MAINS level. so, concentrate more on these parts. the physical chemistry is not much involved in these two parts of chemistry. Just know the formulae  in the physical chemistry. so, that you can answer the questions that are interlinked between both physical chemistry and these two parts..

Hope this will helps you...!

GOOD LUCK...!
