You would probably have to repeat the 7th grade, because you need to have a certain GPA, and 2 F's mean that you are only able to get 2.0 GPA, maximum. Otherwise, you'll fail. So, you have a very small chance of passing.
1.That's up to your mom or whoever teaches you. 2. I'm homeschooled and I can't get F's on quizes or tests, but on lessons it's fine as long as I can go back and reread it and learn it. 3. 3 of my siblings though were held back two in 9th grade and one in 4th for not doing the work.
Being held back is completely up to your educator, but also don't stress if your having trouble don't be afraid ask someone, I'm sure you're doing fine if you only have two F's. Keep up the great work.
