no it is not difficult, its just that it is not studied using the right approach.
if u strt panicking by thinking it is diff, u will never find it easy
rxns are the only part which require some learning.
instead of cramming all the reactions , try to delve into them
Spend 5 minutes on each reaction , observe it carefully , use ur imagination and try to associate it with something funny or weird or like that. almost 50 % reactions can be learnt this way.
u can write the rxns u find diff, on a piece of paper and carry it with u , whenever u get time, try to recall the rxns frst n then look at the chit.
and most imp revise the rxns by writing them.u need 2 hav all the rxns on ur tips
