How to make better grades than in the past?

First of all dont stress. Thats the key.
1#pay attention , listen in class . You learn more in class in 15 min then you do in 1 hour at home.
2# make heaps of notes it helps to memorize . Do not make excuse i will remember that dont need to write it down cuz in 99% you wont . Highlight the importent information and lable basic staff that you need to remember .
3# get a gooooood night sleep and in the morning dont forget to eat goooood healthy breakfast .it will help concentrate and will improve cordination ( almonds are good for memorizing )
4# dont leave anything for the last minute, be prepare the day before . Try to keep it simple - you can use a planer to know when do you have you homework due and your exams. Simple but smart. P.s if you have trouble understanding staff , find some videos on youtube . Thats a success. GOOD LUCK

1- Make a space for homework oriented activities, if you make it in your bed it will make it harder to sleep because psychologically you are in your work space. I would suggest doing homework at the kitchen table or in the living room, or if you are close to it, a library. 2- Make a schedule. It is important to have time for fun but it is just as important to get your homework done. Make a designated time for school work and for play. DON'T make it where you are packed down to every minute, make it a tentative schedule, packed schedules tend to stress people out. 3- Ask for help if you need it. If there is a question you don't understand, don't wait for someone else to raise their hand, go ahead and ask. Also if you need a tutor that is fine, find someone who can help you out.These are all I can think of without being repetitive. Good Luck!
