"First, I'm a Civil Engineering graduate of Mapua Institute of Technology, an ABET-accredited university back in the Philippines and I'm currently an Engineer-in-Training here in the US so Mathematics is really my core.

Regarding experience, I actually had a lot though most were off the record professionally. I was an adviser of Center for Student Advising of my university and it's literally a tutorial center. Higher batches from second year and beyond can teach everything they can to anyone for free. I was a member for 3 years until I graduated and I've taught almost every preparatory engineering subjects there is: from Algebra, Trigo, Physics, Mechanics, etc.

Professionally, I had an actual experience as a professor because while I was waiting for my board examination, my university hired me to teach 6 classes (4 Trigonometry and 2 Solid Mensuration) for the Department of Mathematics consisting of 40 students each. I taught for 3 months (1 term for a Quarterm System of Education) before passing the board exam and flying here in the US.

I'm an engineer at heart so I bleed math. Besides from competing since high school, I've already taught hundreds of people either individually or by group from Algebra to Differential Equations." less...
