Hard worker / experienced/ tallented/ Students with strong desire to pass Uni but somehow struggle

I was a straight A student back in highschool and passed University Entrance Exam with Distinction. I have always wanted to help students but I was on another career. I discovered I have the tallent during the lockdown period after I started helping my nephew and niece who were in highschool to make a significant change in their academic endeavor and pass uni. I make them fall in love with Physics and Maths first by showing them the passion behind knowledge, I worked hard to cover the prerequisite knowledge they missed in previous classes which helped boost their confidence to solve current problems. From my vast life experience I managed to make them to be self motivated to achieve their goals in life which is the main driving engine to success. It worked, and somehow I learned I have the potential along the way, and I thought may be I can be of help to others as well.
