Revisiting Courses and/or Tracks

More than you'd guess probably. My feeling is don't move onto something else until you've mastered the thing you are currently on. If you don't have that confidence, go back to it.

I think it's important to work at the pace that suits you. At the moment I've stopped going through the Beginner Android track to give me time to catch up on concepts I haven't quite mastered yet.

If you are somewhat like me, it will really help you!

Sometimes, when everything is new in a video/course, I tend to focus my mind in understanding new concepts, but then when I watch, review, exercise again, I notice certain things that in the first moment I really didn't realize were mentioned/applicable, etc.

A very good idea indeed.

Anyway, when we are working as developers, web developers, etc., we will have to be coming back and reviewing our code like how many times? A lot :)

If you could see my notes on some of the JavaScript courses I've taken here, you'd feel better! The courses are very good and explain the concepts clearly, but I had to watch some of the videos two or even three times and slowly muscle my way through the challenges. Learning how to program in general and learning new programming languages require repeated exposure for most people, so you're in good company.

I rewatch content all the time. There's a lot of little things that are easy to forget or miss altogether. A few rewatches usually gets me back to where I need to be!
