Log your questions as you studyShould you stop the lesson for every question?

It's hard to stop and chase a question while you're trying to stay focused. If you break off every time something puzzles you, you lose the thread, and lots of questions answer themselves a few minutes later.

So instead, keep a question log as you go: write the date, then just the time and "Qu" each time something doesn't make sense.

• The lessons are always there, so go back to 10:17 whenever you like and ask yourself what was being said at that point.
• You might think you'll have forgotten by then, but you've committed it to paper, so you'll remember. It's like tying a piece of string round your finger: you know what it's for because you physically did something to remind yourself.
• After rewatching, you may find you don't need to ask after all. If you still do, ask Sparky — the AI tutor answers from these notes and links you to the exact section.
• Be proactive. Try to answer your queries yourself first. You get far more out of it when you find the answer yourself.
