Like if I were to read all 6 textbooks on this site how far would I would be in a standard college course on electronics? 1 year through? I'm a noob to electronics but I read the textbooks because I think its interesting and I might want to pursue it as a career so I'm just curious.

 

It is a bit difficult to put an accurate time frame to the material. IMHO, it is more than freshman level, but less than junior level.
