Thanks for the plug and I'm glad the book worked out for you.

I've been keeping the book up to date and "maintaining" by fixing typos and improving certain explanations. If anyone else is interested, you can see a extended preview here: https://minireference.com/static/excerpts/noBSmathphys_v5_pr... and the concept map from the book is here: https://minireference.com/static/conceptmaps/math_and_physic...

I also recently released shorter book focussing just on high school math chapter, for people who are not interested in calculus but still want a refresher on the basics. You can check it out here with fancy new cover design and website: https://nobsmath.com/ (it's basically Chapter 1 of the big book) Aussi disponible en Français https://nobsmath.com/fr/

I really like the "placement exam" in this, that tells you where your weaknesses are and what to focus on. I feel like this is the kind of tool I want when someone says "I suck at X".

For reference, here is the placement exam from the front of the book preview: https://minireference.com/static/excerpts/noBSmathphys_v5_pr...
