If you are not good in engineering, you do not get good grade (actually good learning) just by pouring the thick bucks ($8000/year) and ultimately you won't get job if you don't have good understing of your subject matter.

My suggestion is go for the one where you can do outstanding (good is not enough in this country). I think this is possible only if you really like that field. For excellent achiever there is job, there career, there is future, there is everything. But life is yours, final chioce is yours.
