Hey bro, it is possible to to score if u study hard and go through all the materials thoroughly.
Let’s start with physics. Phy. Is all about derivations and reasoning questions,if u done these two parts u will score more than 75% in phyiscs. Numericals carries abt 15–20 marks. Don’t waste ur time on numericals. Secondly, Optics is the most imp. chapter from 2nd book especially microscope part so go through it. After this, that radioactivity chapter and logic gates. In 1st book , cover up guass’ theorem plus it’s applications, chptr 1&2 derivations.
Chemistry somewhere sucks as one can’t learn all the organic reactions. Well leave it.
In chemistry, generally numericals come from the starting four chapters and the tough ones are from solutions. Mostly questions are reasoning type, so when u read any chapter go through all its reasoning portion. Um..coordination compound, for this chptr u may practice that energy level diagrams and the hybridisation one and that naming part also.
