Download and take the test preview as if it were an actual test.  Start as early as you can so you can check your answers and get help.

Cover up the multiple choice answers until you have attempted the question, if the answer you got is not there, you already know you did something wrong.

Don't guess, there is no value in being accidentally correct on the preview.

Once done, open the answer document and grade your test. 

Work on all the questions you got wrong or couldn't finish.  Ask someone for help... parents, math teachers, tutors, Dr. Math on the internet... whatever.

 

Then come to class prepared and confident.
