within in no time.
3.coming to physical &Organic chewmistry concentate more on isomerism and give more waitage to alkanes alkenes &alkyenes.don't study the whole syllabus in physical &don't stress your mind if don't get it leave it move on to other topics.
4.now moving to maths concentrate on the concept and as well as SHORTCUTS in maths do the calculus coordinategeometry first.coz trigonometry is avast subject study selectively.
