Hang in there. Keep working on figuring out the things you are not certain about. Even a score of a 50% at this point is OK. Improve it by 10-15% by test day and you are good. Also remember that each point on the FRQ is important. Don't take them for granted. You have to prove you understand it.
Very proud of the work you have done this year.
It has been a challenging year, but you have risen to meet it. I still believe this will be our finest year when the test results roll in during the month of July.
