Minecraft Education offers a free trial for users in Microsoft-verified academic organizations, which includes 25 free logins for faculty accounts and 10 for student accounts. However, if you're not part of a Microsoft-verified academic organization, you may only have access to 10 free logins. After the free logins are used, a paid license is required to continue playing.
If you are part of a qualifying educational institution, you can explore the option of getting Minecraft Education for free through the trial. Otherwise, there are no official ways to obtain the game for free without violating terms of service.
It's important to consider discussing your interest in the game with your parents, as they may be able to help you find a solution.
