The admissions office of the college you are contemplating HOWEVER (yes, screaming) with so many folk moving to cell phones, tablets and other types of PCs the old ways of computer maintenance (dusting, cleaning, heatsink compound) or in short HARDWARE repair is changing faster than a college can keep up with. Even Windows and it's repair is no more it seems. Folk just reload the OS and move on because the shop rates are that high. Also, repair costs (at least here) can be more than a new PC.
Be careful here. You may find you took a course in buggy whip manufacturing and repair.
Could you please recommend a on line (free if poss) maintenance course?
What would be a good conventional course in a college or night school be?
