Udacity's introductory algorithms course (CS215) covering core algorithm design and analysis, taught in Python. It is free and works through algorithmic ideas and their efficiency.

Commenters point to it as a good, free algorithms course, one calling it a great course that corrected their assumptions about what they knew.

   I recommend going to codeacademy.com and working through the lessons. Then also udacity has some good CS courses for Intro,Algorithms, and Design. All free. Good to get your feet wet get some practice. Then once you've gotten started, can read books on good architecture and patterns like Code…

   Here's a great online course on algorithms from Udacity. I thought I knew all I needed to know about algorithms. I was wrong! **edit** I should add that this course is actually pretty advanced, and you'll have to understand basic Python syntax.

   Hi Randy! I'm an instructor at MakerSquare. If you are exceedingly comfortable with the topics that we present in the prework, you should be fine for Day 1. No need to review prior math classes :) One thing that's not currently in our prework that you may want to check out is algorithms. Udacity…
