SISC Science is the national 3-hour Year 11 science paper sat by Form 5 students across Solomon Islands under MEHRD NEAD, listed from 2026 on the SISCL1 timetable. Schools may not charge an examination fee. MEHRD reports a minimum subject score of 53 out of 100 and a minimum six-subject aggregate of 318 out of 600 for Form 6 selection; the Year 11 national pass rate was 65% in 2025. This bank offers 100 explained multiple-choice questions as an English-language study adaptation, not a simulation of the official written paper.

Sample SISC Science Practice Questions

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

1Which cell organelle is known as the site of aerobic respiration and energy (ATP) production in plant and animal cells?
A.Chloroplast
B.Mitochondrion
C.Ribosome
D.Golgi body
Explanation: Mitochondria carry out aerobic respiration, breaking down glucose in the presence of oxygen to release energy in the form of ATP.
2What is the net movement of water molecules across a selectively permeable membrane from a region of higher water potential to lower water potential called?
A.Active transport
B.Osmosis
C.Diffusion
D.Phagocytosis
Explanation: Osmosis is the specialized passive movement of water molecules through a selectively permeable membrane down a water potential gradient.
3Which enzyme present in human saliva begins the chemical digestion of starch into maltose?
A.Pepsin
B.Salivary amylase
C.Lipase
D.Trypsin
Explanation: Salivary amylase is secreted by salivary glands in the mouth to hydrolyze starch polysaccharides into simpler disaccharides like maltose.
4Which blood component is primarily responsible for transporting oxygen throughout the human body?
A.Platelets
B.White blood cells
C.Red blood cells
D.Blood plasma
Explanation: Red blood cells contain hemoglobin, an iron-containing protein that reversibly binds oxygen molecules for transport from lungs to tissues.
5What primary vector transmits the Plasmodium parasite responsible for malaria in the Solomon Islands?
A.Aedes mosquito
B.Female Anopheles mosquito
C.Housefly
D.Sandfly
Explanation: Malaria is transmitted when an infected female Anopheles mosquito bites a human host and injects Plasmodium sporozoites into the bloodstream.
6Which part of a flowering plant receives pollen grains during pollination?
A.Anther
B.Stigma
C.Filament
D.Sepal
Explanation: The stigma is the sticky surface at the top of the female carpel/pistil designed to receive pollen grains.
7During human breathing, what change occurs in the diaphragm during inhalation?
A.It relaxes and arches upward
B.It contracts and flattens downward
C.It expands sideways without moving down
D.It remains static while only rib muscles move
Explanation: During inhalation, the diaphragm contracts and moves downward (flattens), increasing chest cavity volume and reducing pressure to draw air into lungs.
8What essential biological process converts light energy, water, and carbon dioxide into glucose and oxygen in green plants?
A.Transpiration
B.Photosynthesis
C.Respiration
D.Germination
Explanation: Photosynthesis is the autotrophic process in green plant chloroplasts that uses solar energy to synthesize carbohydrate (glucose) from CO2 and H2O.
9A student views a plant cell specimen under a light microscope using a 10x eyepiece lens and a 40x objective lens. What is the total magnification?
A.50x
B.400x
C.300x
D.4000x
Explanation: Total magnification is calculated by multiplying eyepiece lens magnification by objective lens magnification: 10 x 40 = 400x.
10Why does a wilted plant stem regain firmness when placed in a container of pure fresh water?
A.Water leaves plant cells by osmosis until cytoplasm shrinks
B.Water enters plant cells by osmosis, creating turgor pressure against cell walls
C.Salt molecules actively diffuse into cell vacuoles to harden them
D.Photosynthesis stops, preventing water evaporation through leaves
Explanation: Fresh water has a higher water potential than cell sap. Water enters vacuolated plant cells by osmosis, pushing the plasma membrane against the rigid cell wall to generate turgor pressure.

About the SISC Science Exam

The Solomon Islands School Certificate (SISC) Science examination is the national Form 5 (Year 11) science assessment run by MEHRD's National Education Assessment Division. From 2026 MEHRD lists it on the Solomon Islands School Certificate Level One (SISCL1) timetable. The course integrates biology, chemistry, physics and Earth/environmental science with Pacific island applications, and candidates sit one 3-hour written paper combining multiple-choice, short-answer and long-answer sections. The 100 questions in this bank are an English-language multiple-choice study adaptation covering that syllabus; they are a revision aid and do not simulate the written sections of the official paper.

Assessment

Single question-and-answer booklet, 3 hours plus 10 minutes reading time. All sections compulsory. In the 2020 paper: Section A multiple choice (20 marks, 30 minutes), Section B short answer (60 marks, 60 minutes), Section C long answer (20 marks, 90 minutes), 100 marks in total. Mobile phones are not permitted and correction fluid may not be used.

Time Limit

3 hours plus 10 minutes reading time

Passing Score

MEHRD reports Year 11 subject results on a 53-100 scale, where 53 is the minimum subject score, and a six-subject aggregate on a 318-600 scale, where 318 is the minimum aggregate used for Form 6 selection.

Exam Fee

No fee. The Permanent Secretary's administrative instruction prohibits schools from charging national examination fees to Year 9, Year 11 and Year 12 students. (Ministry of Education and Human Resources Development (MEHRD), National Education Assessment Division (NEAD))

SISC Science Study Tips from Top Performers

1Master core physics formulas such as Speed = Distance / Time, Force = Mass x Acceleration, and Ohm's Law (V = IR).
2Practise the written sections separately — roughly 80 of the 100 marks in the 2020 paper came from short-answer and long-answer questions, not from multiple choice.
3Understand local Pacific issues including coral bleaching, mangrove functions, plate tectonics and tropical cyclone safety.
4Review laboratory safety rules and variable identification (independent, dependent, controlled variables).
5Practise balancing chemical equations and identifying acid-base indicators.

Frequently Asked Questions

What is the SISC Science examination?

It is the national Year 11 (Form 5) integrated science paper set by MEHRD's National Education Assessment Division. Results feed into selection for Year 12 (Form 6).

Is SISC the same thing as SISCL1?

Yes. MEHRD's 2026 national examination notice lists the Year 11 papers under Solomon Islands School Certificate Level One (SISCL1); the older name Solomon Islands School Certificate (SISC) is still in common use.

How long is the SISC Science paper and how is it structured?

Three hours plus 10 minutes reading time, in one question-and-answer booklet. All sections are compulsory. The 2020 paper carried 100 marks: Section A multiple choice (20), Section B short answer (60) and Section C long answer (20).

Is there an examination fee for SISC Science?

No. MEHRD's standing administrative instruction prohibits schools from charging national examination fees to Year 9, Year 11 and Year 12 students.

How are SISC Science results reported?

MEHRD reports a subject score on a 53-100 scale, with 53 the minimum, and a six-subject aggregate on a 318-600 scale, with 318 the minimum aggregate. There is no published 1-to-9 grade scale at Year 11.

Does this practice bank match the official exam format?

No. The official paper mixes multiple choice with written short-answer and long-answer sections. These 100 questions are an English-language multiple-choice study adaptation covering the same syllabus content; they cannot substitute for practising the written sections.
