If you have a firm grasp of the concept, you won't be afraid of any problem!
How on earth should I study math?

There are countless study methods and tips out there, but one thing that is never left out in any of them is the need to understand the concepts.
When you learn addition, you learn subtraction through addition, and when you learn multiplication, you learn division through multiplication.
Just like a story in history, mathematical concepts are connected by a continuum, so if you miss even one concept, you won't be able to fully understand the next concept.
Grasp the unshakable concepts with Summa Cum Laude, a step-by-step learning method.
You will discover the true fun of mathematics and be prepared for various essay-based exams and performance assessments in the future.
