WBST (ATB) Practice Questions (2026) — Free Sample Questions with Answers

Answer: B

The bus that leaves at 7:40 a.m.: Wrong. This bus leaves before Dana can reach the stop at 7:50 a.m.

The bus that leaves at 8:05 a.m.: Correct. It leaves after 7:50 a.m. and arrives at 8:50 a.m., before her 9:00 a.m. deadline.

The bus that leaves at 8:20 a.m.: Wrong. It arrives at 9:10 a.m., which is after 9:00 a.m.

The bus that leaves at 8:45 a.m.: Wrong. It arrives at 9:30 a.m., which is too late.

Check both conditions in the table: the bus must leave after Dana can reach the stop and arrive before her deadline. Only one row meets both.

Answer: B

warm and friendly: Wrong. A warm reply would not make the employee worry that she had done something wrong.

brief and abrupt: Correct. The context clue "just the two words" shows the reply was very short, and the employee's worry suggests it was curt.

long and detailed: Wrong. Two words is the opposite of a long reply.

loud and angry: Wrong. Nothing in the sentence describes volume or anger. The clue is about length.

Look for context clues near an unfamiliar word, such as an example, a definition or a contrast. Here the example ("just the two words") defines it.

Answer: C

Each of the workers who finished early was allowed to leave.: Wrong. This sentence is correct. "Each" is singular, so "was" agrees with it.

Neither the manager nor the clerks were at the meeting.: Wrong. This sentence is correct. With "neither...nor," the verb agrees with the nearer subject, "clerks," which is plural.

The list of supplies that we ordered were delivered Tuesday.: Correct. The subject is "list," which is singular, so the verb should be "was delivered," not "were delivered."

When the bell rang, the students and their teacher left.: Wrong. This sentence is correct. It is a complex sentence with a proper introductory clause and a compound subject.

In long sentences, strip away phrases and clauses ("of supplies that we ordered") to find the real subject before checking the verb.

Answer: B

7.5 hours: Wrong. This subtracts the lunch break twice, or miscounts the time from 7:45 to 4:15.

8 hours: Correct. From 7:45 a.m. to 4:15 p.m. is 8 hours 30 minutes. Subtracting the 30-minute lunch leaves 8 hours.

8.5 hours: Wrong. 8.5 hours is the full time on site, before the unpaid lunch is subtracted.

9 hours: Wrong. This rounds 7:45 to 7:00 or 4:15 to 5:00 instead of counting exactly.

To find elapsed time across noon, count to the next whole hour (7:45 to 8:00 is 15 minutes), count whole hours (8:00 to 4:00 is 8 hours), add the leftover minutes, then subtract breaks.

Answer: C

20%: Wrong. This divides the 50-unit increase by April's 250 instead of by the starting value, March's 200.

50%: Wrong. 50 is the number of units gained, not the percent increase.

25%: Correct. Increase = 250 − 200 = 50, and 50 ÷ 200 = 0.25 = 25%.

125%: Wrong. April's sales are 125% of March's sales, but the increase is only 25%.

Percent change = (new − old) ÷ old × 100. Always divide by the starting value.

Answer: D

8 feet: Wrong. This subtracts the lengths (13 − 5) instead of using the Pythagorean theorem.

about 13.9 feet: Wrong. This adds the squares (169 + 25 = 194) and takes the square root. The height must be shorter than the 13-foot ladder.

18 feet: Wrong. This adds the lengths. The height cannot exceed the length of the ladder.

12 feet: Correct. The ladder is the hypotenuse: h² + 5² = 13², so h² = 169 − 25 = 144 and h = 12.

In a right triangle, a² + b² = c², where c is the longest side (the ladder). To find a leg, subtract: a² = c² − b².
