Best AP to self study?

<p>Hi,</p>

<p>I am a high school freshman and I’m looking to study for an AP test over the summer to then take the test the next year. What would be the best subject for me to study? I currently take all honors classes and I’m in biology, geometry, world history, English 9, public speaking and Spanish 1. I have never taken an AP course but I am going to take Macroeconomics my sophomore year. Also what is the format of the tests and what the best prep book use? </p>

<p>Thanks in advance</p>

<p>I’m doing AP HuG and AP CS</p>

<p>AP CS best book - Barrons + “Be Prepared”
AP HuG - I’m using 5 Steps and Barrons, maybe Barrons flash cards</p>

<p>Thanks. How hard are they?</p>
