"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, since they point to where the trouble is. I answer using very specific examples, illustrating general principles and techniques.

It's too easy to not give enough examples, or leave terms undefined or ambiguous.

* I love teaching and helping people.

* I use my whimsical sense of humor to have some fun ("pretend that lumpy thing I just drew is a circle").

* I make tutoring a conversation, where I show 1-2 steps, and ask if that was clear. Occasionally, I'm not clear enough, so I rephrase!

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.

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.

Here's how many hours I've tutored on Wyzant.com:

For regular or Instant Book sessions, I charge only for the time used, not the time reserved.

If you postpone or cancel regular or Instant Book sessions nicely, I'll void the charge. If you're not nice or blow me off, I may charge 100%." less...
