Different types of problems need to be tackled differently .You need to be skilled in these.
The techniques of dimensional analysis could be applied in a variety of conversion problems. The complex units could be converted using dimensional analysis as well a 3-step problem solving approach in solving a chemistry problem could be like this:
- Analyze the problem - list all the knows and unknowns
- Calculate - now solve for the unknowns
- Evaluate - does the result make any sense?
However, there are a number of complex problems which may require more than 3 steps.
Further there are comprehension problems which test your ability to grasp the things fast and analyze them using relational approach.

petersykes for organic
leave inorganic in the hands of god
u can clear cutoff by reading any 1 of the 3 useless subjects
for that follow first NCERT then ARIHANT ...then anyother book like OP Tondon ,P bahadur etc
these books will be sufficent...BUT DONT NEGLECT NCERT ...DO THAT BOOK THOROUGHLY>>>
try to give some more time to chem ..in these 2 months...like for eg..3 hours for chem 21/2 hours for maths and physics..and if ur a dropper then dont worry ur concepts are clear..and u just need to brush them up...
there lot of time man...and i m sure u will crack JEE ...but dont forget chemistry...giv e equal importance to all 3 subjects
cheers
pls help me..wat shud i do...m very weak in my chemistry....wh ich books..i prefer?? how would i improve my chemistry....???
last year in jee 2009...i got
128 marks in maths
127 marks in physics
3 marks in chemistry
what should i do..i was not able to clear the chemistry cutoff....as whatever i did in chemistry exam got wrong....i lost a lot of marks due to negative marking....
