2 hours of lecture.10 minutes.
The lecture, minus the recap, the board wiped before you copied it, and the projector dying. What is left is the part that turns up in the exercises, short enough to watch before you start them.
What you do with it:sleepthe social eventfinishing the problem set
Free, with an account. No attendance sheet, no guilt, no 8am.
What you do with the time you get back
Nap without negotiating
A genuinely unbothered afternoon nap, taken in daylight, with nobody's syllabus whispering at you. Undefeated.
Go to the social event
The campus event you keep seeing posters for. The one your friends go to while you reread slide 47 for the third time.
Walk around the library
Not to study. Just to walk around it, look busy, and leave. An underrated pastime and a strong alibi.
Do the actual exercises
The unglamorous one. Nobody passes by rewatching lectures. You pass by doing the problems, and this buys you the hours to do them.
Four ways to use a ten-minute video
These don't replace your lectures or your notes. They give you the shape of a topic fast, so the hours you do spend go on the parts that actually earn marks.
- 01
Before the lecture
Ten minutes beforehand and the lecture stops being a wall of new words. You already know roughly where it's going, so you can follow the argument instead of frantically copying slides.
- 02
Straight after
You sat through it. Watch the short version the same day and the ideas settle while they're still fresh, instead of evaporating by Thursday.
- 03
Stuck on an exercise
Half the time you're missing one specific idea, not the whole chapter. Find it in a couple of minutes and get back to the problem, rather than rereading forty pages hoping it appears.

Revision week
Run the whole course back-to-back in an afternoon to find the gaps, then spend your real study time on those. Far better than rereading everything evenly and hoping.
The honest version: watching is the easy part. These exist to free up time for the exercises, which is where the marks actually come from.
Try a questionright now
This one comes straight from the Analysis bank, exactly as it appears at the end of a video. Two buttons, a one-line correction, and you know whether it landed.
If a sequence is bounded, then it converges.
Not quite. It is false: (−1)ⁿ is bounded and never settles. Bounded plus monotone converges — the monotone convergence theorem — and monotone is the half missing here.
It's free. Here's the catch.
There isn't one. Every video and every quiz is open to anyone with an account — the login only exists so the videos are not simply reposted elsewhere, and so I can see how many students actually use this. What keeps it running is hosting bills and evenings of editing, so if it saved you a semester you can drop something in the tip jar.
Who is behind this
I am a master's student at EPFL and have spent a lot of semesters as a teaching assistant. This all started with two conversations in the same month…
