Hey there

I suggest you to make a good timetable by your own as nobody knows your problems better than you. Some points I am suggesting you which you may consider while making time table like pay more attention or hours to the weak subject, do not make strict routine like at 6'0 clock I'll have study a particular chapter as that would never work. So you fix number of hours for each subject and at any cost pay that much hours to those subjects which is most necessary. Regularity is must.

Good luck
