I still stand by my earlier recommendation. The course has been designed to be approached in this way -- yes, you'll miss some questions, but the pacing, structure, and variability of the exam is something you want to learn along the way -- ESPECIALLY if you're starting in the upper-middle range. We've been successful with many many many students following this path, a huge number of whom have scored in the 700+ range.
The tests will reinforce what you're learning in the lectures, and you'll get better at these over time. You won't build long term bad habits, but practicing questions within a test-like structure will help you hone the skills you're learning and enable you to see where you'd apply the techniques you're learning. It will also help you learn to look for shortcuts and faster approaches. (There's no rocket science on the test, and many students would do much better, given an unlimited amount of time, so the timing is really important to practice along the way - )
Your LSAT experience will help with the verbal section. You'll find that it's similar in many ways.
If you want to augment slightly at the front end, then do the Math Essentials Lecture and homework before your first practice exam to shake the dust off of your test-taking skills and math skills. Definitely take a practice test before you begin, so you know where you really need to focus. The sooner the better on that. If you want to weight the front toward lectures and the back toward tests, then do 1 test every 10 days (ish) for the first half of the course, and then ramp up to 1 per week.
Hope this helps!
