If I had to give you another, it would be to pair analyzing and interpreting literature with another harder test, but allow a short break in between on that day.
Using this method, you are knocking out 2 at a time, but only studying for one. This will get you probably 6 tests in 3 sessions. The other method burns through the easy ones in one session- and it will take you 5 sessions for 6 exams.
Good Luck!
