CBSE 12th

As in high school maybe a daunting task for some while easier for others. The best part is that there is no need for you to give up your social life and free time either! With just about two hours (or less). A day, you can move forward to getting a whole report card full of nineties.
Don't skip classes- You'd be surprised as to how much you'll learn and how much studying you won't have to do before exams just by showing up to class! If you must be absent from a class because you are sick or for religious reasons, be sure to catch up and get a friend to get you that day's lesson.
Pay attention. There's no point of you being in class if you're not going to pay attention. Paying attention includes participating in class discussion and taking proper notes which you'll be able to look back to for tests.
Get A Good Nights Rest- Okay, I know it sounds cheesy but seriously think about it. If you wake up disoriented and feel like the world is spinning, how do you expect to be able to pay attention to the words in front of you during a test?
Play to Your Strengths and Interests- If you hate art, don't take art if you don't have to. Choose courses you are good at and like. If you like something, you'll be more committed to it and feel like you put in more effort. Furthermore, you tend to get higher marks in courses you are good in.
Do Your Homework- Doing your homework means that you are up to the course requirements and it gives you your own sense of understanding as to whether or not you need help. Furthermore, some teachers will take notice as to whether or not you do your homework take marks off accordingly.
Study- Ah, the most boring and the hardest part of being a student. It's boring, yes but it has to be done. Just one hour of studying and reviewing the material will get you through. A good tip is to go to the back of the textbook (if there is one) and do the review questions. A way to make studying go faster is to do so with a group who is committed to working. If you're easily distracted, you're better off alone. Be proactive. If there's something in class you don't understand, don't be afraid to ask for help from your teachers or other students. Surprisingly, teachers are willing to set up after-school/lunch sessions with students who are struggling.
Read the Day Before- While studying, it is a good idea to read ahead as to what will be covered the next day. That way, you won't be totally lost the next day because you'll have had time.
