Open the home page of the school network, then log in to your account and return to the home page. There is an educational administration system, click it in, and then look for information. There is a score query in it. After clicking, you can press the academic year or all academic year scores.
If you want to check your grades outside the school, download a VPN from the network service on the home page of the school network, install it on your computer, log in to your school network account at home, and then continue the initial steps.
