14 Sets of Previous Real AJHSME (AMC 8) Tests with Answer Keys
The test became accessible to a much larger body of students. Reiter, and Leo J. The configurations might be most easily defined using absolute value, or floor, or ceiling notation greatest and least integer functions. Perhaps this is a good time to look at the history of the exam, its sponsorship, and its evolution–and important changes to begin in the year The former requires a few applications of the Pythagorean Theorem, whereas the latter requires not only Pythagorean arithmetic, but spatial visualization and manipulation of inequalities solutons well.
It was offered only in New York state until when it became national under the sponsorship of the MAA and the Society of Actuaries. Beginning ineach student was asked to indicate their sex on the answer form. Such a problem could be counted in any of the three categories geometry, combinatorics, or absolute value, floor and ceiling.
THE AMERICAN HIGH SCHOOL MATHEMATICS EXAMINATION: A 50 YEAR RETROSPECTIVE
The table below shows how many problems of each of ten types appeared in each of the five decades of the exam and the percent of the problems during that decade which are classified of that type. Of course the availability of the graphing calculator, and now calculators with computer algebra systems CAS capabilities has changed the types of questions that can be asked.
The scoring system has changed solution the history of the exam. Students whose first inclination is to construct the graph of the function will be led to the answer 2 since in each viewing window, the function appears to have just two intercepts. Note that even the hardest problems in the early years often required only algebraic and geometric skills. But the test continues to use problems involving topics most students encounter only after grade 10, topics such as trigonometry and logarithms.
Thus questions which become more difficult when the calculator is used indiscriminately are becoming increasingly popular with the committee.
In the early years, there were some computational problems. With the advent of the calculator inthe trend from exercises among the first ten to easy but non-routine problems has become more pronounced.
There has been a distinction between wrong answers and blanks since the beginning, first with a penalty for wrong answers, and later with a bonus for blanks. The AMC12 will also be a question, 75 minute exam. It was finally reduced to the current 30 questions in The first such exam was given in That is, they are problems whose solutions require only the skills we teach in the classroom and essentially no ingenuity.
At this time, the organizational unit became the American Mathematics Competitions. Scoring The scoring system has changed over the history of the exam.
How about counting problems, geometric probability? In cases like this, we looked closely at the solution to see if it was predominantly of one of the competing types.
Problems involving several areas of mathematics are much more common now, especially problems which shed light on the rich interplay between algebra and geometry, between algebra and number theory, and between geometry and combinatorics. Thus, the version is the 50th. In other words, random guessing will in general lower sollutions participant’s score. In the early s trigonometry and geometric probability problems were introduced.
Many of the geometry problems have solutions, in some cases alternative solutions, which use trigonometric functions or identities, like the Law of Sines or the Law of Cosines. Has there been greater or less emphasis on geometry, on logarithms, on trigonometry? In calculators were allowed for the first time. Have arithmetic problems become less popular?
The AHSME is constructed and administered by the American Mathematics Competitions AMC whose purpose is to increase interest in mathematics and to develop problem solving ability through a ajsme of friendly mathematics competitions for junior grades 8 and below and solutiobs high school students grades 9 through In the s counting problems began to appear.
A very small number of problems are counted twice in the table. As you read below how the AMC exams have evolved, you will see that they have moved towards greater participation at many grade levels, much less emphasis on speed and intricate calculation, and greater emphasis on crtical thinking and the interrelations between different parts of mathematics. For example, a problem was considered a trigonometry problem if a trigonometric function is used in the statement of the problem.
First, it was supposed to promote interest in problem solving and mathematics among high school students. With the increasing need to enable all students to learn as much mathematics as they are able, the AMC has moved away from encouraging only the most able students to participate.
For example, a problem might ask how many of certain geometric configurations are there in the plane. It is interesting to see the how the test has changed over the years. Previous tothe scoring of the exam was done locally, in some states by the teacher-managers themselves and in other states by the volunteer state director. Correct answers will be worth 6 points and blanks will be worth 2 points, so the top possible score is still Many of ajsme recent harder problems in contrast require some special insight.

A few problems of this type are double counted. In the 80s problems involving statistical ideas began to appear: Referring to the Special Fiftieth Anniversary AHSME, problems , , , , , , , and  would all have to be eliminated for this year’s contest, either because of the graphing calculator’s solve and graphing capabilities or because of the symbolic algebra capabilities of some recent calculators.
For example, consider  below:
