Choose a subject or the available combined paper. The 30- and 90-minute timers are practice options, not a claim about the institution’s current format. These original questions are not past papers. Answers stay in this browser; no school grade, coin balance or enrolment changes.
Set 1 of 1 available paper set.
5 written questions: 2 can be checked against the answer key; 3 need a guardian or subject teacher to review. Science is an optional separate paper.
Set your rehearsal time
The timer starts when you choose Start model test.
You can leave or finish early without losing game progress. If time expires, the draft is kept and review opens. A timer is a rehearsal aid and cannot prevent leaving the page or changing a device clock.
Your written questions
Work on paper and enter the requested answer. Explain reasoning in the longer response boxes. Keep your work if you want a teacher to review it.

photosynthesis
Photosynthesis transfers light energy into chemical stores.
Science reasoning where the target school requires it
Model answer and review guidance
No. It requires comparable conditions, not identical biological responses.
Review both the conclusion and its reason. It requires comparable conditions, not identical biological responses.
Science reasoning where the target school requires it
Model answer and review guidance
Individual plants vary, so repeats help show whether the pattern is consistent.
Explain variation.
Science reasoning where the target school requires it
Model answer and review guidance
An observed difference might reflect the individual plants rather than the light treatment.
