Can you do what you learned?
A: It could be that you have attended lessons in a class, studied online/from home or just listened to an 'expert' tell how something is done. For each lesson:
Take notes - in a book, mental note or make a recording.
B: After the lesson:
- study the notes and check details from a book or online. Edit/add to your notes appropriately.
- Practice out any procedure given, or work through the examples as done by the expert in class.
- Confirm that you are able to reproduce the results, including those given online or in books.
C: Extend your practicing by working through application for the concepts covered in class, seeking assistance when required.
D: Do this after every lesson, and before the next lesson.
This is the discipline required to learn and to put into practice what you learn.
