Hi Kajal,
Being a Class 11 student, it might be difficult to sort your time for each subject as many new topics are introduced to you and that you might experience extreme pressure. I suggest sorting your subjects according to your liking towards that subject.
If you are an early bird, never start with a complicated subject for you as it might make you feel sleepy again. Start your morning with a subject which might be difficult but you enjoy it. If you are a night owl, never study a complicated subject at night. Before start studying count from 1-30 backwards. It will increase your concentration.
After that, when you are a bit tired, reward yourself with a 5-minute break and start with a subject you like. Don't try to cover a whole chapter in a day. It's easy to forget which you surely don't want. Instead of completing a portion, you decide that when you study the rest, give a quick overlook to the already revised part. Try using quick sticky notes and highlighters as colour attracts our minds and easily remembers the topic.
Use different pens to write your extra point notes in your book itself so that when you revise the notes you made are always in front of you. And always remember to reward yourself even for small achievements. It will surely motivate you.
I wish you luck!
