I'm just a guy who loves making educational materials. I made the Spanish study guide for my own use and will continue to update it over time with additional information and corrections, so keep checking back for the latest version! I will also upload guides to other subjects as I make them.
If you have any questions, suggestions, or corrections, feel free to contact me at firstname.lastname@example.org. My goal is to make my guides perfect and to compact as much information into as small a space as possible.
