Dear student!
Sorry, but you haven't mentioned the name of the education borad you are studying in. Whether it is CBSE, ICSE, or any State board. Somit is quite difficult to provide you with the time table. But, in order to prepare well for exams, these are the basic steps which you should follow -
* Know the syllabus very well and make a timetable accordingly.
* Follow the time table strictly.
* Make small notes besides while studying.
* Practice and solve as many questions and problems as you can as per the question paper pattern.
* Revise the weak points every day.
* Clear doubts with the help of a teacher regularly.
* Take care of your health.
If you follow only this much, you will surely get good marks in the finals. In oder to get the timetable of the exam, you can visit the respective official website and get it there.  You can practice the questions from the books containing question banks and previous year question papers of the respective stream and subjects. Hope this helps.
Good luck!
