study as much as you can. make sure to have enough studying time. have at least 25 minutes to study, then 5 to 15 minutes to rest your brain from all of the hard work. make sure to ask your teacher to help you with any questions or concerns you may have. pay as much as attention in class and have neat notes to study later. also get enough rest and eat healthily. make sure to not stress out also because that'll make you lose track of what you are studying for. I also recommend you to look up ways to study better buy studyquill .I'm sure that'll help too. now I hope this helps you, try your best and good luck.
