Hello! I have used this site in the past to answer a few questions I had. But never once have I considered using the vast knowledge available to help me figure out where to start. I am entering school with a duel major in Engineering and Physics. I was looking at the job http://www.linkedin.com/jobs2/view/15411884 [Broken] to give me a general description of what I should know. Kinda like using a template to know where to go and what I should know. But the problem is, this is all the end game. I do not understand half of what I read and lookup. I have tons of pdf files on a flashdrive that I read but I cannot understand it because I am ignorant on half of it. Does anybody know of files or SOMETHING that will not shatter my bank account in search of how to understand it all? If I look at it all and try to know it now, it will not be as hard when I come to it via classwork.
