No calculator allowed only scratch paper, some formulas are provided on test screen. There is also a timer on test screen you must click on it to see how much time you have remaining.
On the computer adaptive subtests, examinees are advised against randomly guessing as time is about to expire. The current time limits for each subtest have been established to allow as many examinees as possible to finish the test without time expiring. If an examine has worked diligently and quickly on a given subtest, random guessing will, in most cases, be more detrimental to scores than the penalty received for not completing the entire test.
Math Skills Test (MST). Measures the examinee's ability to: Apply mathematical processes to solve equations. The math skills assessed by the ASTB subtests include arithmetic and algebra, with some geometry. The assessments include both equations and word problems. Some items require solving for variables, others are time and distance problems, and some require the estimation of simple probabilities. Skills assessed include basic arithmetic operations, solving for variables, fractions, roots, exponents, and the calculation of angles, areas, and perimeters of geometric shapes.
Reading Comprehension Test (RCT). Measures the examinee's ability to analyze written information and form logical conclusions: Reading comprehension items require ASTB examinees to extract meaning from text passages. Each item requires the examinee to determine which of the response options can be inferred from the passage itself. It is very important for examinees to remember that incorrect response options may still appear to be ‘true,’ but only one answer to each item can be derived solely from the information in the passage.
Mechanical Comprehension Test (MCT). Measures the examinee's ability to Perceive and understand the nature of physical relationships, Solve practical problems related to mechanical principles Items contained within the mechanical comprehension portion of the ASTB include topics that would typically be found in an introductory high school physics course and the application of these topics to a variety of situations. The questions in this portion of the test gauge examinees’ knowledge of principles related to gases and liquids, and their understanding of the ways in which these properties affect pressure, volume, and velocity. The subtest also includes questions that relate to the components and performance of engines, principles of electricity, gears, weight distribution, and the operation of simple machines, such as pulleys and fulcrums.

Sample Questions
1.Sally can paint a house in 4 hours and John can paint it in 6, how long does it take them to paint it together (easy). USE
GRAMMAR HERO on YouTube for all these word problems
2. John scored 64 on his first test and 74 on his second. His third test was 10 points more than his fourth test, and his fourth test was the average of the first three tests. What was his average of all five tests? Again, use GRAMMAR HERO on YouTube, as well as the
ORGANIC CHEMISTRY TUTOR for more word problems.
3. Bob went fishing and 7 of every 8 casts did not get any bites. 1/3 of the casts that did bite reeled in a fish. How many times does he need to cast his pole to get a minimum of 8 fish?
4. A ranch has horses and ponies. 9-tenths of all the ponies have horseshoes. Half of the shoed-ponies are Icelandic ponies. How many ponies are on the ranch? A. 17 B. 23 C. 18 D. Then I realized that if half of the shoed ponies are Icelandic, that means that there must be an even number of shoed-ponies. So all you have to do is multiply each answer by 9/10 and see which one spits out a whole and even number.
5. Simply (2(x+2)^2)^2 + 6x (x-4)^2 all divided by 4. Not exact numbers but it's similar to test.
6. "what is
some single-digit number in binary" 0-12 in binary. "binary is base-2 because 1 is 0 and 1 together, and 0 = 0, and 2 = 0 and 1 and 1 (so in base-4 binary, how is 7+8 expressed?" just study what base-2 and base-4 binary is.
7. Sarah’s final grade is made up of 20% from 3 tests, 10% from homework, and 30% from the final exam. She scored 72 and 84 on the first two tests, her third test was 10 points less than what she scored on the final exam. Her class grade was an 80. What was her final exam score?Challenging grade questions involving percentages and weighted averages
8. DICE PROBABILITY
