Test yourself under exam conditions
Drop up to 6 PowerPoint, PDF or Word files, 50 MB each, and choose the chapters, the kind of questions, the level (recall, application or reasoning), how many questions and the timer. The questions stay hidden until you start, and the clock runs until you hand in.
It is the step after reading: once you have understood the material, the mock exam shows whether you can answer on it, in time.
A grade out of 20, and what to study next
Once you hand in, or the clock runs out, your answers are checked and you get a grade out of 20, with every answer next to the right one. Multiple choice and written answers are both marked. Then comes what to study next, weakest chapter first.
Every attempt is kept, so you can sit the same chapters again before the real exam and see how far you have come.
See the mock examFollow the lecture live, slide by slide
When your presenter runs the lecture on Diaposi, you follow the slides on your own phone, tablet or laptop, go back to any slide already shown, take private notes and mark what to review. Nothing to record and nothing to upload afterwards. Your presenter does not use Diaposi? Upload the deck they show and follow it page by page, with your own notes and an explanation on every page.
Gemini Notebook has no live mode; a lecture recording can be added to a notebook as a source afterwards.
See how following a lecture worksEvery correction points to the page
Your results start with a grade out of 20 and a strip of coloured squares, one per question, each opening that answer. Every correction shows your answer beside the right one, the criteria a written answer met or not yet, and where the answer sits in your course: document, chapter and pages.
What to study next lists every chapter the mock exam asked about, weakest first, with the pages to reread. Sit it again, try new questions on the same chapters or pick others: chapters you have practised show your last grade out of 20, so you can go straight to your weak spots.
See the mock examAn explanation on every page of the deck you are taught from
Upload the deck your presenter uses and each page opens a Learn more card: the page explained simply, another example, what you need to know first, a question to check yourself and references to explore. It follows the language of your slides.
The summary gives the idea in one sentence, what the document covers and what you should be able to answer by the end. Quiz yourself on the chapters you choose, with an explanation after every answer, and treat the references as suggestions to check before you cite them.
