Math: I train students for math competitions, and can cover most topics for algebra, geometry, trigonometry, calculus, and statistics. I also teach linear programming and how to solve LPs on Excel.
Chemical Engineering: My most commonly taught topics are on material balances and thermodynamics. I also tutor on using Excel VBA to create numerical solvers and optimizers. I tutor on a few other general engineering topics including operations research, and statics.
Chemistry: I tutor on inorganic chemistry, physical chemistry and thermodynamics, with a little analytical chemistry.
Physics: I tutor on mechanics, energy, electricity, and some basic astronomy.
