Hello Farheen !!

It is very important to make a schedule which you have to follow in order to get a MBBS seat.

If you are planning to self study it surely means that you will be spending most of the time in house. I will advice you to go for walks or play something so that you don't get depressed, homesick or bored.

Now coming to the preparation part , since you will not avail any coaching you will not be having their material . Therefore you need to refer some books . NCERT should be well understood and on fingertips .

Remember there is no fixed time for study , whenever you feel like dig into it . Don't force yourself to books . Mediation can help in these situations.

After this go for some higher books like GRB for chemistry , DC Panedey or HC Verma for physics , Trueman or Dinesh for Biology .

It is also important to solve a lot of questions for which the All in One series is a good one .

Also if possible get yourself registered to some online platform where you can solve mock test papers .

Following all this for a year is not easy , you need to be determined and hard working. Spend some time alone thinking about yourself and what to do next . 

All the best.

Hope this helps .
