Prepping for math courses after 10 years

<p>Hi there. I am returning to hopefully get my bs in construction engineering this fall. I took pre-calculus in high school but tested only high enough to get into trig. I was string in math and always enjoyed it. My question is can anybody recommend a good book to review my algebra 2 and trig in preparation for my trig class this fall. It is my goal to feel extremely confident in going into this class and moving on to calculus 1 in the spring. Thank you so much for any input </p>

<p>Here are some free placement tests that can help you determine what high school math topics you need to review or learn before taking calculus:

<p>Thank you very much</p>

<p>I think reviewing Khan Academy videos gave me adequate preparation for college math and beyond a little bit.</p>
