How to prepare for AMC 8 and Ace it

7 Tips to prepare for AMC 8 exam


What is AMC and who can take it?

AMC stands for American Mathematics Competition. AMC 8 can be taken by any kid in Grade 8 or below. Usually, it's taken by the students in Middle School for it requires the in-depth knowledge of topics covered in Middle School. AMC 8 is challenging even for Middle School kids. One would have to be an advanced 4th or 5th grader to be able to take it in Elementary school.


Where can you register and take the AMC 8?

AMC 8 is usually administered in schools, but some RSM centres also do it. If you want your kid to take the exam you can contact your school or your local RSM centre.

If you are homeschooling or if your school does not host the AMC 8, you can also look into the MAA website once the registration opens to see a list of your local schools that host it. You can call them to see if they will let you take the exam there.


When does AMC 8 2021-22 exam take place?

It takes place in the middle of November. I recommend that kids start preparing for it in the summer.


June 9, 2021 Update: For the academic year 2021-2022 the AMC 8 exam will be held between Jan 18 and Jan 24.


When to expect the results

Official scores will be sent out in February of 2022 for the academic year 2021-22.


Benefits of taking the AMC 8 exam

I love the AMC 8 exam. Preparing for it helps develop the problem-solving skills in middle schoolers. One also becomes extremely comfortable with Algebra and Geometry if they prepare well for this exam. Hence I tell all my students to go for it.


If you do really well, your school might also let you take the advanced AMC 10 and AMC 12 exams.


Here are some methods I used when I helped my students prepare for AMC 8. Some materials have also been mentioned by my friends who've prepared their kids for it.


Edit: I've updated this post on Apr 17, 2021 so it contains a little more details and might not match up to the infographic.


Materials and Books you can use for AMC 8 Preparation

1. Pre - Algebra book from Art of Problem Solving - This is a great book that covers the basics of most of the topics that you need to master for your AMC 8. This book will also change your mindset about problem-solving if you are a beginner. Once you're done with this you can move on to the other introductory books by AOPS - Introduction to Algebra, Number Theory, Counting Probability and Geometry. You need to do about the first 10 chapters from Introduction to Algebra, Geometry and Counting and Probability. Once this is done you can finish each of the books.


2. Volume 1 - the Basics from Art of Problem Solving - This contains more advanced topics needed to ace the AMC 8.


3. Past exam question papers - you can find these in the AOPS website itself. This tells you what to expect. Also, you’ll find that every year the paper is getting more challenging. Papers older than 2010 are really easy.


As you do the papers, you need to make a not of the time. Always time your papers. Keep your answer sheet aside. Now you can do the same paper without the time limit. Now make a note of both your scores. The first one will tell you about your score under pressure and the second one will give you an idea of your subject knowledge. Every time you do a paper you will keep track of the answers that you got right and wrong in an excel sheet in the following format.

Put a tick if you got that question correct and an 'x' if you got that wrong. After you finish 5 years of papers or so, have a look at all the questions you got wrong. Work on these and see if you find a pattern where you go wrong. See if there is a particular topic that bothers you and work on that.


4. Online Courses by AOPS - You can enrol in these courses to help you prepare. You need to be highly disciplined to gain from these courses though. Go through their assignment problems every week without fail. Now they have in-person classes in some centres as well.


5. Alcumus by AOPS - Alcumus is free to use. You do need to set up an online account if you don't already have one.

How I use it - If you've already done Pre-Algebra and just need to review it, you can definitely use Alcumus. Just set the setting at hard/ insanely hard (depending on the level you like) and do the problems. Reviewing done real fast.


6. Brilliant is also supposed to have practice materials, but I haven’t specifically used them for practice.


7. Residential Math Summer camps - If you really want to crack it and be in the top 5%, there are some residential summer camps. To even get to these camps or benefit from them you should be an experienced problem-solver. You are looking at 3 weeks of your summer with at least 6–8 hours of math every day. That’s what it takes to crack it.


8. Hire a Math Competition coach/ tutor: If you think the summer camps are too expensive, you can still prepare at home with a guide/ tutor. I still believe summer is the best time to prepare for AMC 8 or Math Counts because your mind is free to absorb new material without too much distraction.


I’ve used the first 3 materials with my kids (just the Pre-Algebra book without the others) and boosted their scores from almost nothing (score between 0–6) to be in the top 15–25% within 3–4 months. I do wish I had more time to prepare them though.


Now that the preparation is done here are some tips to keep in mind before the exam.



Tips for taking the AMC 8 exam:

1. There are 25 questions and 40 minutes to finish the exam. The questions are usually in increasing order of difficulty. Keep track of the time when solving the questions. Estimated time for solving the questions are as follows- a. first 10 questions less than 10 min. b. 11-20 questions less than 17 min. c. 21-25 questions less than 10 min. d. use the rest of the time for rechecking your answers


2. There is no penalty for guessing. So do NOT leave any questions unanswered. Just take a guess :)


3. Figures are not necessarily drawn to scale. So please don’t measure the length of lines etc. (unless you have no other idea to solve the problem)


4. AMC 8 does not require the use of calculators. So if you are getting into some lengthy decimal calculations, you might want to re-read your question/ recheck your method. You should not be getting into lengthy calculations. Either your calculation is wrong or there is a trick to solving it.


5. You shouldn’t be spending more than 3 minutes in any question unless it’s towards the end. If you are stuck in any question and you don’t think you are going to get an answer in the next min or so, move on. You can come back to this later. All questions have equal weight, so your goal is to solve as many questions as possible.


6. There might be a question or two within the first 15 questions that are easy but consume a lot of time. Come back to that question after finishing the rest of the paper. Do not waste 5 minutes on that question unless that’s the only one you know.


All the very best for your AMC 8.


As you might know I'm Vasudha, an Online Math Tutor. I love preparing kids for various Elementary and Middle School Math Competitions. The kids also enjoy the classes and have fun with preparation. I've helped a kid who was in the bottom 25% to move to the top 15%. I've also helped a kid who had trouble with understanding the paper to the top 25%. Last year, 4 of my students went to the state round in Math Counts.
