What is the right way to study theoretical subjects ?

[u/Imaginary-Spring-779]

All subjects can be classified into either quantitative or theoretical, or a combination of both

1. quantitative - (maths, operations research, applied maths ) which involves formulas and problem solving

2. Theoretical - like a story, doesn't involve any problems ( social studies, biology )

3. Combination of the above ( physics, etc.) which involves concepts along with problems

For quantitative subjects, I study the introduction, I note the formulas, and I start practicing the problems.

The more I solve problems, the more perfect I become in that subject.

For the combination of both quantitative and theoretical subjects, I follow the above strategy; most of the theoretical part can be remembered after solving the problems, as they are related.

But I don't know what's the right way to study theoretical subjects, for example I have a subject named industry 5.0 - 2 credit subject in which I have to study about all industrial revolutions, different technologies of all revolutions, etc,, it has many diagrams, stories, examples but no problems. it's a book of 180 pages .

I fail to recall in the exams.

I have completed learning how to learn by Barbara Oakley. In that she tells to revise periodically.

But I want to know, should I take notes while studying for the first time? Or not take notes? How many times should I study? Should I make bullet points? I am completely blank on this aspect. I need your help

I need to know what mistake I am making here. Also

Please give your valuable advice
