KJSEA Integrated Science and Pre-Technical Studies: Last-Minute Revision Tips

Updated 24 October 2026

Two of the subjects Grade 9 learners sit at the end of the 2026 Kenya Junior School Education Assessment (KJSEA) are the practical, hands-on ones: Integrated Science and Pre-Technical Studies. They fall on the last two days of the week, which means learners reach them tired, after four days of papers. A clear plan for these two subjects matters for that reason alone.

When the Papers Are

According to the official KNEC 2026 KJSEA timetable:

• Thursday 29 October: Integrated Science Paper 1 (905/1), 8.30 am to 10.10 am, followed later in the day by Social Studies and Creative Arts and Sports.
• Friday 30 October: Pre-Technical Studies (912/1), 8.30 am to 10.10 am; then the religious education papers from 11.10 am; then Integrated Science Paper 2 (905/2), 2.00 pm to 3.00 pm, the last paper of the week.

The Pre-Technical Studies project (912/2) was done at school earlier in the year, so Friday’s written paper is the remaining piece. Integrated Science is split, so a learner has to keep science fresh from Thursday morning to Friday afternoon.

Integrated Science: Learn the Diagrams

Integrated Science brings together biology, chemistry and physics ideas from Grades 7 to 9. In the last days, the best return comes from what examiners ask again and again.

• Labelled diagrams. Practise drawing and labelling the main ones from memory: the human digestive and breathing systems, the parts of a flower, plant and animal cells, a simple electric circuit, and laboratory apparatus. Use a sharp pencil, label lines that touch the part, and never shade unless asked.
• Experiments. For any experiment in your notes, be able to state the aim, the apparatus, the steps, what was observed and the conclusion. Questions often describe an experiment and ask what was observed or why a step was done.
• Observations versus explanations. “The limewater turned milky” is an observation. “Carbon dioxide was produced” is the conclusion. Questions ask for one or the other, so read carefully.
• Units and symbols. Know basic units such as metres, kilograms, seconds, newtons and degrees Celsius, and the symbols for components in a circuit.
• Health and environment. Topics such as nutrition, diseases, drug and substance abuse, and conserving the environment are part of the curriculum and easy marks if revised.

Pre-Technical Studies: Safety, Tools and Drawing

Pre-Technical Studies is about how things are made, used and kept safe. Learners who have done well at the project often underrate the written paper, so revise it properly.

• Safety first. Know the common workshop hazards, the safety rules and the protective equipment for each. Safety signs and their meanings are frequent questions.
• Tools and materials. For each common hand tool, know its name, what it is used for and how to care for it. For materials, know their properties and why one is chosen over another for a job.
• Technical drawing. Practise drawing lines, simple shapes and views neatly with a ruler and pencil. Accuracy and neatness earn marks, so bring a ruler, set squares if you have them, a sharp pencil and a rubber.
• Computing and entrepreneurship. Pre-Technical Studies also covers basic computer use and simple business ideas, such as costing a product or keeping records. Read the question data carefully and show any calculation.

A Simple Plan for the Last Days

The weekend before the assessment is the best time for science and pre-technical revision, because from Monday the language papers and Mathematics take priority.

• Saturday and Sunday: one hour each on Integrated Science diagrams and experiments, and one hour on Pre-Technical safety, tools and a drawing exercise.
• Wednesday evening (after Mathematics): a light Integrated Science review of your weakest topics, then rest.
• Thursday evening: 30 minutes of Pre-Technical Studies revision and a quick look at Integrated Science topics you have not yet seen, ready for Paper 2 on Friday afternoon.

Sleep matters more than one more hour of notes, especially by the end of a long week.

Practice Material

The Grade 9 revision papers on CBC Guides include original practice papers for Integrated Science and Pre-Technical Studies, with answers, and the KJSEA section collects the week’s papers and practice by subject. They are practice papers written by the CBC Guides team, not KNEC papers, so use them to rehearse timing and question styles.

For the full week and the rules learners must follow, see our KJSEA 2026 timetable and the KJSEA 2026 revision guide. If your school gives you a different printed timetable, follow the school’s copy, since KNEC’s printed paper is final.
