Sample DGS Practice Questions

Try these sample questions to review concepts for the DGS exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is the value of the arithmetic expression: (-18) ÷ (-3) - 2 × (-4) + (-5)?

A.7

B.9

C.11

D.13

Explanation: Follow standard order of operations: first perform division and multiplication from left to right, then addition and subtraction. (-18) ÷ (-3) = 6. Next, 2 × (-4) = -8, so subtracting this gives - (-8) = +8. Adding (-5) gives 6 + 8 - 5 = 9.

2If a, b, and c are positive integers such that (3a + 4b) / 2 = 5c + 1, which of the following statements must always be true?

A.a is an even integer

B.b is an odd integer

C.c is an even integer

D.a + b is an odd integer

Explanation: Multiply both sides by 2 to clear the fraction: 3a + 4b = 2(5c + 1) = 10c + 2. Notice that 4b is always even, and 10c + 2 is also an even integer regardless of whether c is even or odd. Rearranging gives 3a = (10c + 2) - 4b, which is an even integer minus an even integer, resulting in an even integer. Because 3 is odd, for 3a to be even, a must be an even integer. Parity of b and c cannot be definitively determined.

3If x and y are prime numbers such that x^2 - y^2 = 21, what is the value of x + y?

A.5

B.7

C.9

D.11

Explanation: Factor the difference of squares: (x - y)(x + y) = 21. Because x and y are positive primes and x^2 - y^2 > 0, we have x > y > 0, so x - y < x + y. The integer factor pairs of 21 are (1, 21) and (3, 7). Case 1: x - y = 1 and x + y = 21 yields 2x = 22 -> x = 11, y = 10; here 10 is not prime. Case 2: x - y = 3 and x + y = 7 yields 2x = 10 -> x = 5, y = 2. Both 5 and 2 are prime numbers. Therefore, x + y = 7.

4The sum of five consecutive odd integers is 175. What is the largest of these five integers?

A.35

B.37

C.39

D.41

Explanation: Let the middle integer be n. The five consecutive odd integers can be written as n - 4, n - 2, n, n + 2, and n + 4. Their sum is 5n = 175, so n = 35. The five integers are 31, 33, 35, 37, and 39. The largest integer is n + 4 = 35 + 4 = 39.

5What is the simplified value of the fraction: (8! - 7!) / (6! + 5!)?

A.36

B.42

C.48

D.54

Explanation: Factor out common factorial terms in the numerator and denominator: 8! - 7! = 7!(8 - 1) = 7! × 7. Similarly, 6! + 5! = 5!(6 + 1) = 5! × 7. The fraction becomes (7! × 7) / (5! × 7). The factor of 7 cancels out, leaving 7! / 5! = (7 × 6 × 5!) / 5! = 7 × 6 = 42.

6For a two-digit positive integer AB, reversing the digits produces the integer BA. If AB - BA = 45, what is the value of A - B?

A.3

B.4

C.5

D.6

Explanation: Using place-value expansion, AB = 10A + B and BA = 10B + A. The difference is AB - BA = (10A + B) - (10B + A) = 9A - 9B = 9(A - B). Given that AB - BA = 45, we have 9(A - B) = 45, which simplifies to A - B = 5.

7The four-digit number 4a7b is divisible by both 4 and 9. If a ≠ b, what is the sum of all possible values of digit a?

A.4

B.5

C.6

D.8

Explanation: For a number to be divisible by 4, its last two digits 7b must form a multiple of 4. Between 70 and 79, only 72 and 76 are divisible by 4, so b = 2 or b = 6. For divisibility by 9, the sum of digits 4 + a + 7 + b = 11 + a + b must be a multiple of 9. Case 1: If b = 2, digit sum is 13 + a. The only single digit making this a multiple of 9 is a = 5 (13 + 5 = 18). Here a = 5 ≠ b = 2, which is valid. Case 2: If b = 6, digit sum is 17 + a. The only digit making this a multiple of 9 is a = 1 (17 + 1 = 18). Here a = 1 ≠ b = 6, which is valid. The possible values of a are 5 and 1, and their sum is 5 + 1 = 6.

8Three bells toll at regular intervals of 12, 15, and 20 minutes, respectively. If all three bells toll simultaneously at 09:00, at what time will they next toll together?

A.09:45

B.10:00

C.10:20

D.10:30

Explanation: The time until they next toll simultaneously is the least common multiple (LCM / EKOK) of their individual intervals. Prime factorizations: 12 = 2^2 × 3, 15 = 3 × 5, 20 = 2^2 × 5. LCM(12, 15, 20) = 2^2 × 3 × 5 = 60 minutes. Exactly 60 minutes after 09:00 is 10:00.

9What is the product of the telescoping sequence: (1 - 1/3) × (1 - 1/4) × (1 - 1/5) × ... × (1 - 1/20)?

A.1/20

B.1/10

C.2/15

D.1/5

Explanation: Evaluate each term individually: 1 - 1/3 = 2/3; 1 - 1/4 = 3/4; 1 - 1/5 = 4/5; ... ; 1 - 1/20 = 19/20. Multiplying these gives (2/3) × (3/4) × (4/5) × ... × (19/20). The denominator of each term cancels with the numerator of the succeeding term. All intermediate terms cancel out, leaving only the first numerator (2) and the final denominator (20): 2 / 20 = 1/10.

10If 3^(x + 2) - 3^x = 216, what is the value of x?

A.2

B.3

C.4

D.5

Explanation: Rewrite 3^(x + 2) as 3^x × 3^2 = 9 × 3^x. Substitute this into the equation: 9 × 3^x - 3^x = 216. Factor out 3^x: 3^x(9 - 1) = 8 × 3^x = 216. Divide both sides by 8: 3^x = 216 / 8 = 27. Since 27 = 3^3, we conclude that x = 3.

DGS: Suggested Study Strategy

1Target an average pace of approximately 1 minute and 20 seconds per question to complete the 100 questions within the 135-minute limit.

2Work on both tests: at least 1 net point in each is needed for DGS score calculation under the 2026 guide.

3Practice numerical reasoning, geometry, Turkish sentence meaning, paragraph structure, and logical deductions. Use ÖSYM's released booklet to become familiar with the Turkish text and five-choice format.

4Distinguish our four-choice study questions from the official five-choice questions. In the official scoring system, four wrong answers subtract one correct answer's worth of net points.

Frequently Asked Questions

What is the format and duration of the DGS exam?

The official Turkish-language DGS has 100 five-option MCQs: 50 Sayısal and 50 Sözel, completed in 135 minutes. The DGS assessment itself has no oral, practical, assignment, or case-study component; degree completion and any later university requirements are separate.

Who is eligible to take the DGS?

Applicants normally hold an eligible vocational or open-education ön lisans qualification. Final-year students must have completed graduation requirements other than an internship. Section 2.1 of the 2026 guide also covers recognized overseas qualifications, KKTC routes, and citizenship conditions for placement; Table 2 governs related bachelor's program choices. An interim associate diploma from a four-year-or-longer program is excluded.

How are DGS scores calculated and penalized?

Net points equal correct answers minus incorrect answers divided by four, separately in each test. Section 4.3 of the 2026 guide requires at least 1 net point in each test for a DGS score to be calculated. Standardized test scores and ÖBP form the DGS scores used in competitive placement. This minimum is not a guarantee of admission.

How long is a DGS score valid?

Section 1.6 of the 2026 guide limits 2026 DGS results to placement for the 2026–2027 academic year.

Is this practice bank in Turkish like the official DGS?

The official DGS is in Turkish and uses five choices per question. This independent bank is an English-language MCQ study adaptation with four choices. Instructions and feedback are in English; Turkish passages and choices are retained when interpreting Turkish is integral to the skill. It is not an official translation or a simulation of the exam's format or language environment.
