For example, consider  below: The AMC12 will also be a question, 75 minute exam. The first such exam was given in 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 as well. Note that each problem is numbered by year together with its position on the test in its year of appearance.
Some of the entries above need some elaboration. In cases like this, we looked closely at the solution to see if it was predominantly of one of the competing types. It was finally reduced to the current 30 questions in Thus questions which become more difficult when the calculator is used indiscriminately are becoming increasingly popular with the committee.
In the s counting problems began to appear. With the advent of the calculator inthe trend from exercises among the first ten to easy but non-routine problems has become more pronounced. 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.
A few problems of this type are double counted. Many of the recent harder problems in contrast require some special insight. Correct answers will be worth 6 points and blanks will be worth 2 points, so the top possible score is still The AMC established the rule that every problem had to have a solution without a calculator that was no harder than a calculator solution.
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 series of friendly mathematics competitions for junior grades 8 and below and senior high school students grades 9 through The following table shows the degree of participation and average score among females versus that for males.
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.
For example, the problem above is listed as , which means that it was 196 number 10 on the exam. It was offered only in New York state until when it became national under the sponsorship of the MAA and the Society of Actuaries.
14 Sets of Previous Real AJHSME (AMC 8) Tests with Answer Keys
Has there been greater or less emphasis on geometry, on logarithms, on trigonometry? Previous tothe scoring of the exam was done locally, in some states by ajhsmf teacher-managers themselves and in other states by the volunteer state director.
A very small number of problems are counted twice in the table. In the early years, there were some computational problems. 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.
As you read below how the AMC exams have evolved, you will see that they have moved ajshme 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.
These problems are not counted as trig problems. 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 Such a problem could be counted in any of the three categories geometry, combinatorics, or absolute value, floor and solutuons.
ajhsmd In the number of questions was reduced from 50 to 40 and in was again reduced from 40 to Note that even the hardest problems in the early years often required ajusme algebraic and geometric skills. The test became accessible to a much larger body of students. 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 allowance of the calculator has had the effect of limiting the use of certain computational types of problems. Many of the early problems are what we might call exercises.
For example, a problem might ask how many of certain geometric configurations are there in the plane. The configurations might be most easily defined using absolute value, or floor, or ceiling notation greatest and least integer functions. Reiter, and Leo J. Beginning ineach student was asked to indicate their sex on the answer form.
How about counting problems, geometric solutiobs The new exam AMC10 will be a question, multiple choice contest, with 1 hour and 15 minutes allowed. In the 80s problems involving statistical ideas began to appear: Scoring The scoring system has changed over the history of the exam.
That is, they are problems whose solutions require only the skills we teach in the classroom and essentially no ingenuity. Many early problems involved the simplification of complex fractions, or difficult factoring.
First, it was supposed to promote interest in problem solving and mathematics among high school students. Compare, for example , one of the three hardest that year with number .
AJHSME problems and solutions
In calculators were allowed for the first time. For example, a problem was considered a trigonometry problem soolutions a trigonometric function is used in the statement of the problem.
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. Many problems overlap two or more areas.
