Ideas you can watch.
Each idea is a short lesson round a figure that moves, with a question while it is fresh and practice to close.
Nine cards on polarised light, from the field itself to why a third polariser lets light through two crossed ones.
Marked out of its marks.
Marked the way your course marks: every earned mark counts, slips are named, a later part is marked on your own earlier answer, and an essay is marked against your department's criteria, references included.
Teach it, with the notes shut.
Explain it in your own words and it is checked against the points a good answer makes, down to the exact word: denatured, never killed.
Lightning, in your head.
Quick questions, one tap each, in rounds of 1, 2 or 5 minutes. Great on the go, and every miss feeds your plan.
Memorise, by doing it.
Label a heart from memory, or name the kit for a titration and build it. Each comes back until you have it on 3 different days.
Your notes, made into practice.
Upload notes, slides or a photo of your handwriting, then choose a lesson or a question set at your difficulty.
Every topic fades at its own pace.
Each topic has its own memory curve, so whatever is about to slip comes back first.
Drag across to read any day.
The next question is chosen for you.
Aimed where you get about 8 in 10 right, hard enough to teach you something. Secured, your headline number, is allowed to fall, because memory does.
Planned back from your exams.
About 25 minutes a day, fitted round your week and eased off before each paper. Miss a day and the work moves along.
Intensive, for when it counts.
Every study day to your exams planned, with your sleep protected. It simulates thousands of your weeks and shows a measured chance, never a promise.
What is not here, and never will be.
Three things you will not find in Kerfox.
