# Math OER Turn In Problems  Justice Percentages

The homework you turn in to be graded is the "icing on the cake" that completes a long homework process.

You reviewed your notes. You attempted the example problems in the online notes. You used the problem bank. You did some random problems. Now, finally, you can show off the mastery you have gained from all that work.

Be happy with your written work before you turn it in! Compare your homework with that of classmates. Remember your study skills.

Before using this page, you should have your homework completed on paper. This page is only for submitting your homework. To be short and concise it lacks any diagrams, pictures, or tables needed to work the problems.
