5
The Scores Academic Qualification Rating (AQR) –Scoring emphasis on MST Pilot Flight Aptitude Rating (PFAR) –Scoring emphasis on ANIT, SAT Flight Officer Flight Aptitude Rating (FOFAR) –Scoring emphasis on MST

6
Sample Test Problems No Penalty for Guessing These only demonstrate a sampling of questions found on the ASTB. For a more comprehensive sampling, use one of the ASTB study guides*. *NOMI does not endorse any particular guide.

7
MST (1) Two trains running on the same track travel at the rates of 30 and 35 mph, respectively. If the slower train starts out an hour earlier, how long will it take the faster train to catch up with it? –(A) 4 hours –(B) 5 hours –(C) 6 hours –(D) 7 hours In 1 hour, slower train is 30 miles ahead. Every hour, the faster train gains 5 miles (it is 5mph faster) 30/5 = 6 hours to gain that 30 mile lead

8
MST (2) A naval detachment has enough rations to feed sixteen people for 10 days. If four more people join the detachment, for how many fewer days will the rations last? –(A) 1 –(B) 2 –(C) 3 –(D) 4 16 people for 10 days 16 x 10 = 160 rations = 20 people total 160 / 20 = 8 days Therefore 2 days less Second Technique to solve: let n = # ration days for 20 people 16 x 10 = 20 x n n = 160/20 = 8 days (2 days less)

9
MST (3) A field can be plowed by 9 machines in 5 hours. If 3 machines are broken and cannot be used, how many hours will it take to plow the field? –(A) 7 ½ hours –(B) 8 ½ hours –(C) 9 ½ hours –(D) 10 ½ hours 9 machines take 5 hours, so.. 9 x 5 = 45 hours for 1 machine 9 x 5 = 1 x n (n = # hrs for 1 machine) If 3 are broken: 9 – 3 = 6 machines working 1 x 45 = 6 x c (c= # hrs for 6 machines) n = 45/6 = 7 ½ hours Other Method: n = # hours for 6 machines 9 x 5 = 6 x n 45 = 6n n = 45/6 = 7.5

10
MST (4) A family drove from New York to San Francisco, a distance of 3,000 miles. They drove 1/10 of the distance the first day and 1/9 of the remaining distance the second day. How many miles were left to be driven? –(A) 2,200 –(B) 2,300 –(C) 2,400 –(D) 2,500 First day: Drove 1/10 of 3000 = 300 Therefore 2,700 miles remaining Second day: Drove 1/9 of 2,700 = 300 Therefore 2,400 miles remaining

11
Other MST tips Triangle –180 degrees total –Right triangle has 1 corner = 90° –Complementary angles add up to 90° –Pythagorean Theorem a² + b² = c² Areas Circumference

12
MCT (1) In the figure shown above, X is the driver gear and Y is the driven gear. If the idler gear is rotating clockwise, –(A) gear X and gear Y are rotating clockwise –(B) gear X and gear Y are rotating counterclockwise –(C) gear X is rotating clockwise, while gear Y is rotating counterclockwise X Y idler

13
MCT (2) The maximum weight, W, that can be lifted as shown with a pull of 100 pounds is –(A) 100 pounds –(B) 200 pounds –(C) 300 pounds The number of pulleys indicates the mechanical advantage. In this case, it is 2 2 x 100lbs = 200lbs 100 lb. pull W

14
MCT (3) This one’s a little tougher. Don’t be skerred!

15
MCT (3) A 5-kg wad of clay is tied to the end of a string. A 300- gm copper moving horizontally is embedded into the clay and causes the clay and ball to rise to a height of 0.2 m. The initial velocity v 1 of the ball is nearly A) 6.3 m/s B) 7.3 m/s C) 8.3 m/s KE = ½ mv 2 and PE = mgh. By conservation of energy, KE must equal PE. Solve for v! ½ (0.3 kg )(v 2 ) = ( kg)(9.8 m/s)(0.2 m)

16
RST (1) The voters showed their ____ by staying away from the polls –(A) affluence –(B) apathy –(C) interest –(D) registration -lack of interest

17
OTHER RST HINTS Another type of questions consists of a passage followed by a list of statements. You must identify the statement that is most true. –Hint: DO NOT assume anything, even if you know it’s true. The most correct statement is the one that can DIRECTLY be made from the passage.

18
RST (2) “Genuine coins have an even and distinct corrugated outer edge; the corrugated outer edges on counterfeit coins are usually uneven, crooked, or missing.” –counterfeit coins can rarely be distinguished from genuine coins –counterfeit coins never lose their corrugated outer edge –genuine coins never lose their uneven, corrugated outer edge –the quality of the outer edge may show that a coin is counterfeit There is nothing in the quote to support the first three choices

19
RST (3) “Education should not stop when the individual has been prepared to make a livelihood and to live in modern society; living would be mere existence were there no appreciation and enjoyment of the riches of art, literature, and science.” This quotation best supports the statement that true education –deals chiefly with art, literature, and science –disregards practical goals –prepares an individual for a full enjoyment of life –teaches a person to focus on the routine problems of life The other choices do not address the quotation as much as the third choice.

20
