Every Student Should Take Both the AMC 10A/12A and 10 B/12B!

There are two sets of exams per year, the AMC 10A and AMC 12A, and the AMC 10B and AMC 12B. Both the A and the B versions of the AMC 10 and the AMC 12 have the same number of questions, the same scoring, and the same rules for administration. The only differences are the competition dates and that each version has a distinct set of questions, although the two examinations are designed to be equal in difficulty and distribution of topics.

All students should take both the A-date and B-date AMC tests. The AMC 10B/12B gives a student a second chance to qualify for the American Invitational Mathematics Exam (AIME). If a student does not qualify for the AIME through the AMC10A/12A, then he/she can qualify for the AIME through the AMC10B/12B which provides a great chance at qualifying. See more at:

If a student earns a higher score on the AMC 10B/12B than AMC 10A/12A, then he/she can put the higher score on his/her college application form and resume, and/or write about it in a college application essay. Top 10, well-known U.S. universities and colleges, including internationally recognized U.S. technical institutions, ask for AMC scores on their application forms. Achieving a high score in the AMC will greatly increase the chances of an applicant being accepted to these top universities! See more at:

It is especially important to attend both the AMC 10A/12A and AMC 10B/12B for those students who want to qualify for the United States of America Mathematical Olympiad (USAMO) and the United States of America Junior Mathematical Olympiad (USJMO). Selection to the USAMO is based on the USAMO index which is defined as your AMC 12 score plus 10 times your AIME score. Selection to the USJMO is based on the USJMO index which is defined as your AMC 10 score plus 10 times your AIME score. If you take both the A-date and B-date AMC tests, then the USA(J)MO index will use the higher numerical score. One of our students got a score of 120 on the 2015 AMC 10A, and 138 on the 2015 AMC 10B later. He was able to qualify for the USJMO precisely because he was able to get such a high score on the AMC 10B even though his AMC 10A score did not make the cut. See more at:

We always strongly encourage our students in grades 6 and below to attend both the AMC 10A and AMC 10B. Do not worry about the potential score; it is the experience that is truly valuable, and should not be missed. Students who take more tests tend to have more opportunities and be more experienced to work toward honing their skills! Some of our students in grades 6 and below have qualified for the AIME. It is very impressive. Most of them earned a score of 90 or more out of 150 on the AMC 10, and then received National Achievement Honor Roll Certificates. They got big improvements each year and successfully became AIME qualifiers within 1 to 4 years. See more at:
