I would love to know more about the study process you followed and resources because my wife is in a very similar situation, but here in Norway where they require her Math R1+R2. Great story, and congratulations!
I agree completely, CNTDA is a great book and Jim Kurose, the author does a superb job covering some of the chapter contents in his youtube series (Ch1 to 6.x) from then on, another channel continues each chapter video
Jim Kurose's video lecture series on "Computer Networking, A top down approach". It follows the format of the book (same name). The video lectures are on youtube[1] and can be accessed from his web page[2] as well
The professor does an excellent job at explaining every detail, and the lectures end up being even fun. I've enjoyed this a lot.
The “Mathematics for the Practical Man” series, although old, might be a good resource to consider.
These are the titles I know are out there:
- “Mathematics for the Practical Man”
- “Arithmetic for the Practical Man”
- “Algebra for the Practical Man”
- “Geometry for the Practical Man”
- “Calculus for the Practical Man” -> this last one was the one Richard Feynman used to teach himself calculus (https://physicstoday.scitation.org/do/10.1063/PT.5.9099/full...)
a drastic change, like moving to a diff country/culture could be a good start.
it might not be the end solution, but as a starting point it could help you because drastic (non-toxic) changes tend to put us on our toes, attentive to new environment, etc. specially if you're in a city-country where walking is the norm (i.e. you don't depend on a car (isolated) to get around).
Move to a sunny country like spain (southern spain, works). there are non-lucrative visas you can get without much hassle. good luck
