We're in the home stretch for the June 6 SAT and the June 13 ACT. You should be finishing up your preparation by now. Here's something you should do by this coming weekend - take an entire practice SAT or ACT, while adhering to the time limits for each section. You really need to become accustomed to doing the problems under time pressure of the sort you will experience on the actual exam(s).
You want to get an idea of what you can and cannot do in the allotted time, such as how to budget the 25 minutes you have to write an SAT essay, what math questions you can solve in a minute or so, and which ones to skip, even if you CAN do them with unlimited time, and what reading and writing questions you can and cannot finish in the allotted time.
You also need to know what you need to review in the remaining time. You can always learn a few math or grammar facts, or learn a few more standardized test tricks, before the test. Trust me, doing a little thing every night before the test is MUCH more effective than trying to do every little thing THE night before the test. Good luck!
