How Tiaotiao learns

Watching a lesson is the easy part. Understanding lasts only if you work with it. These are the five habits I use.

Start with a question.
Every lesson begins with one real problem. Try it for two minutes before you watch.
Go slowly through the basics.
It's tempting to hurry through them. I don't, because everything later depends on them.
Make it simple.
“To be lazy, or nicely put: simplify the problem.”
Look for the one idea inside the problem.
Sum it up.
Keep one notebook. Write each problem in one line.
“Sum them up and problems get easier.”
Check the common mistakes.
Every lesson lists the mistakes students make most often. Add your own.

How to study with these lessons

Redo the examples a few days later.
Don't use the video. Write your answer first, then check it against the video. Rewatch the part where you got stuck.
While you watch, follow the reasoning.
See how each problem is solved. Solve it yourself afterwards, not while the video plays.
Come back to the good problems later.
The second time, you notice more details, and sometimes a better method. The problems in your notebook (step 4 above) are the ones worth redoing.
Practice one topic at a time.
Make each topic solid before you move on. Use full past papers to check yourself and to warm up before the exam, not to learn new topics. If your school sets mock exams, follow its schedule.
