u know every person on this earth is unique........so don't get depressed..........study for hours not matters what matters how efficiently u study......
first of all do not make time table in boring manner......it should be energetic......
prepare your shedule like short term goals ( weekly and daily targets) and long term goals ( monthly targets)...............(depending upon your capacity)
monthy targets may be finshing of 4 topics,or three topics etc. weekly target finishing of one topic.....daily target may be finishing of one or two sessions(10 or 15 problems).........
weekly target u set on sunday........then set target of monday on sunday...finsh it and then on monday set target for tuesday.....and analysis of the work of monday ( kiya ya nahi kiya...then tick for done and cross for not done).......by this way after two three weeks u will be able to find your perfomance.........
try to reduce the crosses.........(but if u prepare only one shedule for always....u will not be able to follow it after 3 or 4 days this happens with most of us)...daily targets will help u a lot.
i will say two lines
"Be bold and take the whole responsibilities on your Shoulders becoz u r the creater of your destiny"
