Worked through The Princeton Review Algebra 1, Geometry &amp; Algebra 2 Unlocked studiously. I got a great basis for all, but each book does not go too in depth. I used online resources like IXL while self-tutoring, but this was a great foundation.<br>Overall, very impressed with this book.<br><br>P.S<br><br>Great for the SAT &amp; ACT alone! SAT &amp; ACT like questions are in each chapter and concept.
