CU Boulder vs. Penn State

[pearlmom]

My son has to make a decision soon. He got into Penn State aerospace engineering. He also applied to CU Boulder for aerospace but got admitted into Arts & Sciences. We were told that he can do a Intra University transfer into aerospace engineering. Does anybody know about that? Is it worth the risk? He is also accepted into San Jose State, U of Kansas, U of Cincinnati, Wichita State, U of Arizona. boulder and penn state are at the top of his list. Did anybody went through the IUT process at boulder? Any thoughts appreciated:))))
