Expert Tutor: Math, SAT/ACT/GRE/PSAT, SQL, Python, VBA, Excel & Linux

David L.

Why I'm a good tutor:
* I know my material. That's how I got a Physics PhD and excelled at software tech support.
* Patience, empathy and praise for my students.
* I love questions: they point to trouble spots. I answer with very specific examples, illustrating general principles and techniques. It's too easy to give too few examples, or leave terms undefined or ambiguous.
* I love teaching and helping people.
* I use my whimsical sense of humor to have fun ("pretend that lumpy thing I just drew is a circle").
* With math, I write every step on a miro.com whiteboard, which is much better than Wyzant's whiteboard.

I tutor in 3 areas:
MATH
* 18 years of tutoring Algebra 1 thru Calculus.

TEST PREP
* Preparing students for the Math and Science sections of the SAT, the GRE, the ACT, and the PSAT.

SOFTWARE
* I teach complete SQL courses, including joins and subqueries. I have MySQL, PostgreSQL, SQL Server & Oracle servers ready to go, and in 5 minutes, I can get you practicing SQL on SQLite on your computer.
* Python, including web scraping (with Selenium) and working with databases. Sorry, no Data Science or Pandas.
* Linux, Bash scripting, awk, sed, grep & regular expressions.
* I've done many insane things with Microsoft Excel and VBA.

I've been told I'm great at communicating with people at any level of understanding.
I'll put you at ease, and happy to work at your pace.
