Welcome to Veritas Prep!There's is actually a tool under the “Practice Test” section of your TrueTrack account that lets you enter in your exam date, and it will calculate when you should take your practice exams. You can pair that tool along with the schedule. Of course if you feel like you need more or less time before the exam, simply move your lessons up/back a bit as your schedule permits. Also it may reference, taking an ARCO practice test. Some time ago, ACRO was replaced with GMAT Life.
Please do not hesitate to contact us at headquarters if you have any additional questions.
Hope this helps!
