You can definitely utilize technology to help you through the standardized test prep process - it’ll literally be at your fingertips during any down time that you may have. The first question we usually get is whether a student should take the ACT or the SAT. The best way to check this is to go through several questions of each section of both exams so that the student can get a feel for which they prefer. Most people can easily come to a conclusion on which exam "speaks to them" more. Then, I'd go all in! After all, study for 2 exams?? In some cases we may suggest a swap to the other exam if the practice scores aren't quite matching the academic rigor achieved at school.
Generally, my first recommendation is go to to Khan Academy, they work directly with the college board on SAT test prep. However, there are tons of apps out there as well that are interactive and give you lots of opportunities to practice test questions. We've done a bit of sleuthing for you to weed out the apps that don't have much usage or are poorly put together. I'm an android, so these are all through the Google Play Store. Hopefully a few of these will work out for your needs.
Note of caution - apps are a great way to get breadth. However, once you spot a weakness, you'll need to drill down to really understand how to solve the problems that you're most commonly getting wrong. These apps sometimes do not allow for you to do that in the most productive way.
