I am a licensed chemical engineer of the Philippines. My favorite subjects are Mathematics, Chemistry and Physics. I am interested to share my knowledge to help students solve Mathematics, Chemistry or Physics problems.

If there's anything about Mathematics, Chemistry or Physics that you would like help with, just try me. I usually begin by outlining the discussion. Next I introduce the basic principles and concepts with basic examples on each. Afterwhich, I discuss the solution to the problem assigned to the student. I am open to comments or questions throughout the discussion. As assessment, I give a seatwork problem to the student (with only slight modification to the original problem) so that I can check if he/she understands my learning.
