Not a problem, we are always happy to help!
Regarding taking practice tests, it really depends on your schedule. Of course, it would be great to take one practice test a week, however you should also block time within a day or two to analyze what you learned from the tests. You can find this info from one of our previous blog posts (http://www.veritasprep.com/blog/2011/09 ... -schedule/
Take practice tests — and analyze them!
Students often hit the first part but completely neglect the second. Any time you block 3-4 hours on your calendar to take a practice test, make sure that you have 1-2 hours within a day or two to analyze what you learned. While the experience of taking the test is helpful – it builds stamina, familiarity, etc. – the real value of that test is that it gives you insight into where you need to improve. What mistakes do you make under pressure? How can you better allocate time across the section? Which concepts escaped you when you had to be ready for everything and couldn’t just tune your mind to “today is an algebra day?” Practice tests are an essential component of your study plan, but mainly because they give you an opportunity to learn about yourself. Make sure that you take time to extract that full value from each practice test.
Hope this info helps!
