I need major advice..

Hello CC,
To start this off I am a 10th Grader and set to graduate in 2021.

Let me tell you about my situation, I am a homeschooled student I surprisingly was let into the 10th Grade even after a nearly D average freshman year. Being homeschool I use to think I could just sit in front of my computer and not doing my work until it’s too late and with that mindset I got my work turned in late or just didn’t turn it in at all resulting in me pretty much failing everything. I couldn’t even tell you what my GPA might of been so anyways I just want help to get on the better track so I can graduate and get into a decent college, I really wish I didn’t mess around in my freshman year and I deserve the consequences. I have to at least get a B average this year so that my GPA can greatly improve (hopefully). I know I probably left out some key things but I am in a hurry so if there anything that you guys need to know to help me then please tell me. ANYTHING HELPS.

Why are you homeschooled? It would not seem that homeschooling is working for you…you are not keeping up with the work and your parents are not enforcing it. You seem like you would do better with a more structured environment.
If you have to be homeschooled, then figure out how to create more structure.
