Sample GH-OHCS Graduate Entrance Practice Questions

Try these sample questions to test your GH-OHCS Graduate Entrance exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1If all administrative assistants in the Civil Service must complete a computer literacy course, and Joyce is an administrative assistant, which of the following is the MOST logical conclusion?
A.Joyce must complete a computer literacy course.
B.Joyce is already computer literate.
C.Complete computer literacy is only required for Joyce's promotion.
D.Only Joyce is required to complete the computer literacy course.
Explanation: This follows a basic deductive syllogism (All A are B; C is A; therefore, C is B). Since completing the course is mandatory for all assistants, Joyce, being an assistant, must complete it.
2What is the next item in the alphabet series: A, C, F, J, ...?
A.N
B.O
C.P
D.M
Explanation: The pattern is based on increasing alphabetical gaps: A (+2 letters) -> C (+3 letters) -> F (+4 letters) -> J. Therefore, the next step must be +5 letters from J, which lands on O.
3If it rains, the civil service entrance exam is postponed. The exam was not postponed. Which of the following must be true?
A.It rained, but the venue had a shelter.
B.The exam was held in a different city.
C.It did not rain.
D.The exam was cancelled entirely.
Explanation: This is a classic modus tollens logical argument (If P, then Q. Not Q. Therefore, not P). Since the postponement (Q) did not occur, the condition of rain (P) must not have occurred.
4In a certain code language, the word CIVIL is written as DJWJM. How would the word SERVE be written in that same code?
A.RDUUD
B.TGTVG
C.SFSUF
D.TFSWF
Explanation: Each letter in the word CIVIL is shifted forward by one position in the alphabet (C->D, I->J, V->W, I->J, L->M). Shifting each letter of SERVE forward by one letter yields TFSWF.
5Statement: 'Please turn off your mobile phone during the Civil Service Graduate Entrance Examination.' Which of the following is a logical assumption behind this statement?
A.Some candidates will bring mobile phones to the examination hall.
B.Mobile phones are the only source of distraction in an exam.
C.All candidates will turn off their phones automatically without any announcement.
D.No candidate knows how to turn off a mobile phone without guidance.
Explanation: An assumption is an unstated premise. The request to turn off phones only makes sense if we assume that candidates possess mobile phones and will have them in the hall; otherwise, the instruction would be pointless.
6Complete the analogy: Clock is to Time as Thermometer is to _______.
A.Weather
B.Temperature
C.Heat
D.Mercury
Explanation: A clock is a tool specifically designed to measure time. Similarly, a thermometer is a tool specifically designed to measure temperature.
7Five candidates—A, B, C, D, and E—are seated in a row facing north. C sits immediately to the right of E. A sits to the left of B, but to the right of C. D sits immediately to the left of E. Who is sitting in the middle of the row?
A.B
B.E
C.C
D.D
Explanation: Let's determine the placement. D is immediately left of E -> (D, E). C sits immediately right of E -> (D, E, C). A sits to the left of B but right of C -> (D, E, C, A, B). This fits all 5 candidates in a row: D, E, C, A, B. The middle candidate is C, which is at index 2.
8Syllogism: - No politicians are civil servants. - All civil servants are graduates. Based on these statements, which of the following conclusions must logically follow?
A.No graduates are politicians.
B.All graduates are civil servants.
C.Some politicians are graduates.
D.Some graduates are not politicians.
Explanation: Since all civil servants are graduates, and no civil servants are politicians, the graduates who are civil servants cannot be politicians. Therefore, there must be some graduates (specifically the civil servants) who are not politicians.
9Three statements are given: - If Ama passes the civil service exam, then Kofi also passes. - If Kofi passes, then Yaa does not pass. - Ama passed the exam. Which of the following conclusions is logically sound?
A.Yaa did not pass.
B.Kofi did not pass.
C.Yaa and Kofi both passed.
D.We cannot draw any conclusion about Yaa.
Explanation: Since Ama passed, we can deduce Kofi passed (first premise). Since Kofi passed, we can deduce Yaa did not pass (second premise). Therefore, Yaa did not pass.
10In a secret code: - '3a, 2b, 4c' means 'clear blue sky' - '2b, 5d, 6e' means 'blue and white' Which code represents the word 'blue'?
A.3a
B.2b
C.4c
D.5d
Explanation: By comparing the two sentences, 'blue' is the only common word, and '2b' is the only common code. Therefore, '2b' must represent 'blue'.
