You’ve bubbled in your last answer; a large chunk of homework is off your plate, but you should be doing more. Having scored the test, you gauge how you’ve done compared to past tests and your overall goals. To be more productive, however, read over the answer explanations to the problems you got wrong. Your goal is to get a better score on the next test, and one way to improve is to understand the mistakes you made so you don’t repeat them. For example, the ACT is repetitive, with similar question types from test to test. Learning a few simple grammar and mathematical rules can go a long way to improving your score.
Secondly, look for patterns in what you have done wrong. Do you always incorrectly answer the math questions with variables on the SAT? Learning one math strategy can remedy this weakness. Your tutors will do their best to identify weaknesses so they can then teach you tactics that address them. This is no substitute, however, for spotting these patterns yourself, which allows you to better understand your errors and makes you more conscientious about fixing them.
A little effort beyond merely attending class and taking practice tests will greatly impact your score.
