How to self-study physics and electrical engineering without going to college? You can buy used textbooks and study it and when you're stucked, can you go to the nearest college and get tutored? For the experiments and hands on training, can you go to the nearest college and do the experiments? How much will they charge you if they require fees?
You will be required to get enrolled to pay for classes. You can self-study theoretical courses, but experiments are usually conducted alongside with general courses. Fees depend on the rank of the university offering classes. In any case, if you want to be hired as a professional, you will need to have a degree, an official documents stating that you have passed required classes. Moreover, students studying enjineering, are required to go through internship. I don't know how can you do this without attending the college? I am a self-studying person myself, but this is a really hard way to go.
In the former Soviet Union those who wanted to be physicists - theorists, could have passed Landau's exams in theoretical physics (Lev Davidovich Landau - Nobel Prize laureat in 1958 for his theory of superfluididty of Helium II). They had a chance to get hired for a job as theorists afterwards, even without completion of formal academic education. But as I know, this happened only with one person among his scholars.
