I am the example that a student has no good environment to study and achieve high academic achievement. I know "no pain, no gain" is an old-school slogan, but It still works. Hope I can reduce the time and pain you have to get over.
Nowadays, I started to have blockchain / gamefi classes.
In my class, I will help students to understand what's the key point in a subject.
My students can learn chemistry and biology in fewer classes, then you can have more time to study other subjects such as mathematics or English.
Graduated from KMU, over 5 yrs as a senior high school home tutor.
In fact, I didn't have the motivation to be a cram school teacher when I was a university student. Then I find teaching and learning is interesting after I teach several students. I want to understand what's the most effective way of learning.
