Primary focus to build the basics concepts of any subject.

For example Maths :
What is the objective of a chapter / lesson
What we will learn
Why do we learn what we learn
How a formula is derived and its simplification.
Ways to remember a formula / a concept
How to easily derive subsequest theorem from previous theorem.
How to identify and note down the key points.
How to memorise the various formulas and identify the usage / implementation of each formula in a given question.

Most of the above points are applicable to Science subjects as well.
It is key to understand the basic concept rather than just memorizing the formulas.

Be my student, I will ensure you understand above points and their importance.

All the best !
