<p>So I'm a junior who screwed up REALLY BADLY on the AMC 10.. I basically did the first 19 and did not check the earlier questions (i missed numbers 5,7,11) while spending the rest of my time on the last few questions, so I scored 18 points less than i expected. I also took the AMC 12 but scored around 10 points lower than the cutoff.</p>
<p>Last year, I did some practice tests and that was it. This year, I really want to make AIME but I am wondering: do the AoPs books really help? I have a pretty busy schedule so I am not sure if I have enough time to study from them. Also, besides the AoPs books, are there any materials that would help me (besides practice tests)? My biggest weaknesses are: geometry and combinatorics. </p>
<p>First of all, I suggest you ask this on the artofproblemsolving.com, where you’ll probably get many more answers. And yes, AoPS 1 & 2 both help a lot, and the Intro/Intermediate subjects are even better for subjects you’re not familiar with. They’ve helped me improve <em>so</em> much. You should also consider AoPS online classes if you’re willing to spend the time and money. Good luck!</p>
<p>However, if you want more material, I would definitely recommend the AoPS books. The summer before my junior year, I read through most of AoPS Volume II, and I learned a lot from it. I wouldn’t really recommend the subject books until you’re comfortable with most of the material in this book. It has two chapters relating to geometry and two excellent chapters on combinatorics, perhaps the best chapters in the book. There are about 15-30 practice problems at the end of each section, as well as some extra assorted problems at the end of the book.</p>
<p>Of course, taking practice AMCs is also a good way to prepare, especially to get used to the format. The AMCs for 2010 and 2011 were significantly harder than those in previous years, so don’t feel bad if you didn’t do as well as you would have liked.</p>
