We do a few things. First, we improve our students' content ability. The SAT and ACT are both content-driven tests now, and the days of getting major jumps from little tricks are gone. We do have a few tricks, but the bulk of the work comes from actually getting better at algebra, grammar, etc. Next, we try to remedy any particular weaknesses a student has. For example, if he or she is running out of time on the reading section, we do some things to help the student either read more efficiently or pursue a strategy that doesn't involve reading every part of every passage. Finally, we are all about spending time in official practice tests. Knowing the underlying content is great, but there is no substitute for doing real tests problems. Having the student go over official problems that he or she missed with an expert instructor is probably the most effective way to spend time once the basic content has been covered.
