Dude,           If u wanna pursue ur career in Chemical engineering,I would highly recommend u to join University of Minnesota-Twin Cities.It is one of the best universities for chemical engineering and recently it has adapted a scheme for international students where international students need to pay only $14000(actually the tution is around $22000 but this year they have reduced for international students).So,dude spending $15000 in University of Oklahoma and University Of Minnesota-twin cities makes a huge difference.If u can,try to manage to make funds and go to that university.Its a great chance for the folks who dream to be a chemical engineer........for more information u can visit its webpage and also don't forget to visit usnews.com to see the ranking of that university.............hope u will make a wise decision.......Goodluck!!
