acc to my perspective , if routine will be given to you , then you will be burdened, thats what my thought regarding routine,
see, suppose u have maximum 1 hr to do maths per day in routine , and u picked maths , in 1 hr u only covered 1 question , or 2 ques after that u have to stop maths forcefully as u are bounded with a routine .
so, dnt follow any routine as such as they will restrict your chapter timming .
but Make sure you are studyiung each and every subject , everyday ,
and also revising that at the wekend .
language subject u can read 3 times per week , but rest all should have to per day , biology , 2days once will be OK , if your fundamental are correct .
do make sure you are not missiing anything per day .
and at the time of sleeping recall whatever u studied per day , that will give u a sensation that u studied something and gained something today ,
ALL THE BEST .
AT LEAST 3-4 HOURS OF STUDY IS MAXIMUM FOR BOARDS .
