Question

If a final is worth 100 points, how many percent of my grade is it??? Thank you

Answer 1

That depends on how your teacher grades. For example, your teacher may count tests for 60% of your quarter/semester grade. Ask your teacher!

Answer 2

I really don't now, but if you failed it would drop your grade very low.
Or if you did good, your grade would probably go up one grade or more depends.
