Sample Sri Lanka Teachers' Service Graduate Open Exam Practice Questions

Try these sample questions to test your Sri Lanka Teachers' Service Graduate Open Exam exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Find the next number in the logical sequence: 2, 6, 12, 20, 30, ...

A.36

B.40

C.42

D.48

Explanation: The sequence is generated by adding consecutive even numbers: 2 + 4 = 6; 6 + 6 = 12; 12 + 8 = 20; 20 + 10 = 30. Therefore, the next term is 30 + 12 = 42. Alternatively, the pattern can be expressed as n(n+1) for n starting from 1.

2Complete the following analogy: Lighthouse : Ship :: Traffic Light : ?

A.Pedestrian

B.Highway

C.Motorist

D.Intersection

Explanation: A lighthouse guides and directs ships to ensure safe navigation. Similarly, a traffic light guides and directs motorists to ensure safe driving and road crossing. Motorists are the primary operators navigated by traffic lights.

3If the word 'TEACHER' is coded as 'VGCEJGT' in a certain code language, how will the word 'STUDENT' be coded in the same language?

A.RTTCEMS

B.UVWFGPV

C.TUVFGPU

D.UTVEFOU

Explanation: The coding pattern is to shift each letter forward by two positions in the alphabet: T(+2)=V, E(+2)=G, A(+2)=C, C(+2)=E, H(+2)=J, E(+2)=G, R(+2)=T. Applying the same pattern to 'STUDENT' gives S(+2)=U, T(+2)=V, U(+2)=W, D(+2)=F, E(+2)=G, N(+2)=P, T(+2)=V, resulting in 'UVWFGPV'.

4Three of the following four word pairs are alike in a certain way and form a group. Which is the one that does NOT belong to the group?

A.Classroom : Desk

B.Library : Book

C.Laboratory : Experiment

D.School : Student

Explanation: In the pairs 'Classroom : Desk', 'Library : Book', and 'School : Student', the second noun represents a physical object or person that is housed or located within the first location. In contrast, 'Laboratory : Experiment' pairs a location with an action or process rather than a physical occupant or item.

5Read the statements: (1) All teachers are writers. (2) Some writers are poets. Which of the following conclusions logically follows from these statements?

A.All teachers are poets

B.Some poets are teachers

C.Some writers are teachers

D.No poet is a teacher

Explanation: Since 'All teachers are writers', it means the set of teachers is a subset of writers. Consequently, some of the writers must be teachers, which makes 'Some writers are teachers' logically true. The other conclusions cannot be definitively proven from the premises.

6A teacher walks 4 km due North from the school, turns right and walks 3 km. How far is the teacher from the starting point in a straight line?

A.7 km

B.5 km

C.6 km

D.3.5 km

Explanation: The walking path forms a right-angled triangle with a vertical leg of 4 km and a horizontal leg of 3 km. The straight-line distance is the hypotenuse, calculated using the Pythagorean theorem: sqrt(4^2 + 3^2) = sqrt(16 + 9) = sqrt(25) = 5 km.

7In a certain code, the word 'BLUE' is written as '2-12-21-5'. How is the word 'RED' written in the same code?

A.18-5-4

B.17-4-3

C.19-6-5

D.18-6-4

Explanation: The code represents the numerical position of each letter in the English alphabet: B=2, L=12, U=21, E=5. For the word 'RED', the alphabetical positions are R=18, E=5, and D=4, which yields '18-5-4'.

8In a school, 60% of the teachers drink tea, 50% drink coffee, and 30% drink both. What percentage of teachers drink neither tea nor coffee?

A.10%

B.20%

C.30%

D.40%

Explanation: Using the set union formula: P(Tea or Coffee) = P(Tea) + P(Coffee) - P(Both) = 60% + 50% - 30% = 80%. The percentage of teachers who drink neither is the complement of this union: 100% - 80% = 20%.

9Find the odd one out among the following Sri Lankan cities based on administrative classification:

A.Colombo

B.Kandy

C.Galle

D.Katunayake

Explanation: Colombo, Kandy, and Galle are major historical and administrative Municipal Councils (cities) of Sri Lanka. Katunayake is classified as an Urban Council (principally known for the international airport and free trade zone) and does not hold Municipal Council status like the other three.

10If the price of a textbook increases by 25%, by what percentage must a student reduce their consumption of books to keep the total expenditure on books unchanged?

A.20%

B.25%

C.15%

D.30%

Explanation: Let the original price be P and consumption be C. New price is 1.25P. To keep expenditure (Price x Consumption) constant: 1.25P x NewC = P x C. This simplifies to NewC = C / 1.25 = 0.8C. A new consumption of 0.8C represents a reduction of 20%.

3Review Sri Lanka's geography and administrative boundaries, such as the major rivers (Mahaweli), mountain peaks (Pidurutalagala), provincial capitals, and district structures.

4Memorize key pedagogical milestones: Jean Piaget's cognitive stages (concrete operational, conservation), Vygotsky's ZPD and scaffolding, Skinner's operant conditioning, and Bloom's Taxonomy cognitive levels.

5Understand the current structure of the Sri Lankan education system, specifically school categorizations (like Grade 1AB, 1C, Type 2, Type 3) and the roles of the National Institute of Education (NIE) and National Education Commission (NEC).

6Practice mock tests to build pacing. Since both papers have a tight 1-hour time limit, managing your time is critical to finishing all questions.
