# FAQs - AMC 10/12

Q. AMC 10/12 #1. What score do you have to get on the AMC 8 to be invited to take the AMC 10?
A. There is no invitation from the AMC 8 to the AMC 10 or AMC 12, Rather, with the AMC 8 Reports we send an AMC 10/12 information brochure, and an AMC 10/12 registration form to the Contest Manager of ALL schools which participate in the AMC 8. No school or student needs a special invitation, nor is any minimum score required. The AMC 10 and AMC 12 are both open competitions.

Q. AMC 10/12 #2. When will the AMC 10/12 results come back by email to the schools?

Q. AMC 10/12 #3. What’s covered on the AMC 10?
A. The AMC 10 covers mathematics normally associated with grades 9 and 10. To challenge students at all
grade levels, and with varying mathematical skills, the problems range from fairly easy to extremely difficult. Approximately 12 questions are common to the AMC 10 and AMC 12. The AMC 10 assumes knowledge of elementary algebra; basic geometry knowledge including the Pythagorean Theorem, area and volume formulas; elementary number theory; and elementary probability. What are excluded are trigonometry, advanced algebra, and advanced geometry. We recommend students study prior year copies of the AMC 10 contest and solutions. You can purchase a CD from the AMC with all the previous decade's contests to see what the AMC 10 contest is like at h

Q. AMC 10/12 #4. What’s covered on the AMC 12?
A. The AMC 12 covers the high school mathematics curriculum, excluding calculus. To challenge students at all grade levels, and with varying mathematical skills, the problems range from fairly easy to extremely difficult. Approximately 12 questions are common to the AMC 10 and AMC 12.

Q. AMC 10/12 #5. Are logarithms covered on the AMC 10?
A. Since logarithms are not usually considered part of the grades 9 and 10 mathematics curriculum, and are usually considered part of advanced algebra, logarithms do not appear on the AMC 10.

Q. AMC 10/12 #6. What calculators are allowed on the AMC 10 and the AMC 12?
A. Calculators are not allowed on the AMC 10 and AMC 12 contests. The 2007 AMC 10 and 12 were the last contests to allow the use of a calculator. All subsequent exams at all levels will not allow calculator usage.

Q. AMC 10/12 #7. Can a student take both contests?
A. Yes, as long as a student is eligible to take the appropriate contests. That is:

• A 10th grader or below can take the AMC 10 A and the AMC 10 B
• A 10th grader or below can take the AMC 10 A and the AMC 12 B
• A 10th grader or below can take the AMC 12 A and the AMC 10 B
• A 10th grader or below can take the AMC 12 A and the AMC 12 B
• An 11th or 12th grader can take the AMC 12 A and the AMC 12 B

However, in order to do this the school would have to register for both dates and order contest bundles to have the contests on hand.

Q. AMC 10/12 #8. Who can proctor the contests?
A. The proctoring of the AMC 10 and AMC 12 contest should be by

1. In the first preference, a math teacher at the registered school
2. In the second preference, a teacher or administrator at the registered school
3. In the third preference, a college or university teacher of mathematics or a responsible adult not
associated with or related to any of the participants who is a math club or team coach for the group of participants.
4. In the fourth preference, a responsible adult not associated with or related to any of the participants such as librarian, clergy, etc.
5. The proctoring of the contest must take place in a public building, (e.g. school, library, college or university, church).
6. The proctor should not be related to any of the participants.

Q. AMC 10/12 #9. Can a school register for both dates?
A. Yes, but the school will have to pay the appropriate registration fee for each contest date, and purchase the contest bundles for each date. The problems on the A and B contest dates are different. Note that approximately 12 questions are common to the AMC 10 and AMC 12 on a single date, so a student cannot take the AMC 10 and the AMC 12 on the same date.

Q. AMC 10/12 #10. What if a school registers for one date, then later wants to change the registration to the other date?
A. Although we discourage a change in date because of the extra handling and potential confusion, nevertheless a change in date is permitted, before the contest materials are sent, as long as time permits according to the registration schedule and as long as the corresponding change in registration fee (plus any change in bundles) is paid. Increases must be paid at the time with charge card, both to expedite changes and to eliminate billing costs.

Q. AMC 10/12 #11. What if a student is sick or absent or at another school activity on the date of the A contest? Can the student take the B contest?
A. Yes, if the school has registered for the B contest date and has contest bundles available for the contest, a student can take the second contest.

Q. AMC 10/12 #12. How can I find the answers or solutions to the questions on the current AMC 10 and AMC 12?
A. Your contest manager has a Contest Manager's Envelope with the solutions to all the problems on the AMC 10 and AMC 12 contests. Of course, the correct letter choices are also included. Please ask your contest manager to see the solutions guide.

Q. AMC 10/12 #13.  My school only offers the AMC12B. Can I go to another school and take the 12A?
A. Yes, it is true that you can take the "other-date" AMC contest at another school, but only in the circumstances that
(1) you have the express permission of the other school's AMC Contest Manager, and
(2) all local school regulations and permissions allow a student from one school to enter another school.  All responsibility for see that both conditions above are fulfilled falls on the student seeking alternate date.
We do our best to make sure AIME qualifiers are accounted for, but we do not forward school winner scores.  Also, usually the alternate school does not count your score at their school, so you can't be a school winner there either.

Q.  AMC 10/12 #14.  What is the difference in AMC 10A and 10B?
A. Both the AMC 10 A and the AMC 10 B have the same number of questions, the same scoring and the same rules for adminstration.  The only difference is that each has a distinct set of questions, although the two contests are designed to be equal in difficulty and distribution of topics.

For national and regional awards only one award will be issued based on the higher score from the A and B contests. For intramural awards it is possible to win an award for both the A and the B contest.

Q.  AMC 10/12 #15.  Which contest should young, advanced students take?
A. A student in 10th grade or below who wishes to qualify for the USAMO must take either the AMC 12 A or the AMC 12 B contests in order to be considered for USAMO selection. We recommend that such a student take an AMC 10 contest on one date if possible. A student in 10th grade or below wishing to take the AMC 12 and qualify for the USAMO should have a good problem solving knowledge in advanced algebra, analytic geometry, function notation, logarithms, trigonometry, and complex numbers in order to score well on the AMC 12, AIME and USAMO.
