FOR SCHOOLS · IGCSE, A-LEVEL & CBC
Your lab has twelve benches.
Your class has forty students.
So most of them watch. Sayansia gives every student a bench of their own — choose the apparatus, build the setup, take the readings, get it wrong, run it again. Then set a real past paper and see exactly which mark point your class keeps dropping.
19 EXPERIMENTS · 6 PAST PAPERS · NO REAGENTS · NO ROTA · WORKS ON A PHONE
THE PROTOCOL
Set it, they run it, it comes back marked
Set the practical
Pick an experiment or a whole past paper, assign it to a class, set a deadline. Takes a minute, and no reagents are used up doing it.
Every student runs it
They collect their own apparatus, build the setup in the right order and take their own readings — on a phone, at home, as many times as it takes.
It comes back marked
Answers are scored against the published mark scheme, point by point. Where a mark genuinely needs the supervisor's own readings, it says so instead of inventing a score.
You see where the marks went
Not just who scored what, but which mark point the class keeps dropping — the rinse step, the missing unit, the meniscus read from the wrong place.
THE VIRTUAL BENCH
It doesn't skip the boring parts. That's the point.
Students collect apparatus from a storeroom shelf that also holds the wrong glassware, and find out why a measuring cylinder can't give you a titre. They assemble the setup in order and learn why a burette is rinsed before it's filled. Then they open the tap drop by drop and chase a real endpoint.
Wrong choices are explained, not silently blocked
Rinse before you fill, clamp before you load
Endpoints, gradients and counts from their own run
Calculations marked with hints, not answers
PAST PAPERS
Real practical papers, marked against the real scheme
Each paper is loaded whole — the confidential instructions that tell the technician what to set out, the question paper itself, and the mark scheme. Students sit it on the bench it was written for, with the answer table and the apparatus side by side.
Where a mark depends on the supervisor's own results, it's reported as needing your eye rather than guessed. A score that claims more certainty than it has is worse than no score.

Every question in every paper is runnable on the bench, not just readable.
THE LIBRARY
19 experiments, every one runnable
Full protocol, apparatus list, safety notes, and — the part the textbook skips — what the results should actually look like.
PRICING
One price, per student, per year
Everything is included — every experiment, every past paper, all three syllabuses. Teacher accounts don't cost extra, because a teacher isn't a seat; a student is.
You already own the benches and the technician. This is what makes them reach the whole class instead of the front row.
SCHOOLS WITH THEIR OWN LAB
Virtual bench
per student · per year
- All 19 experiments, with apparatus and setup stages
- Past-paper practicals marked against the real scheme
- IGCSE, A-Level and CBC
- Teacher accounts
Your students' next practical shouldn't be their first practical.
The titration bench is open with no account needed. Run it yourself, then bring your department.
