Of Course you can, for commerce program, major same as concentration.There won't have any difficuties for applying at second year unless your GPA is not enough.
It depends on how many credits you finished end the year.
There have standard
0-5 credit overall GPA:4 Major GPA: NONE
5.5-10 4.5 5.5
10.5-15 5 6
15.5 OR MORE 5 6.5
so, if you did not get the B- when you finish more than 15.5 credit, you won't kick out,but you can not graduate. For you I think you much achieve the C+.
