The Kelley School of Business is a very good business school. You do not need to transfer anywhere to get a great job after graduation. You are already at a great program at a very good university.
At any great university, almost everyone comes in with close to straight A’s. Many, many students will have been the #1 or #2 student in their high school. However, top schools hand out B’s and C’s. Students who might have one or two B’s in their entire lives prior to attending university will suddenly get half A’s and half B’s, or even mostly B’s and a few C’s. This is normal. There will be a few students at top schools who will get straight A’s, but there will not be very many of them.
“In high school, I only had 2 Bs on my transcript”
Yup. This is normal at a top school. In my personal experience, throughout high school I only had three A’s in math and science classes because everything else was an A+. I got to university, and suddenly math and science classes were hard. I got some A’s, a few B’s, and even one C. This is what happens at a top school. I still got into a great graduate school.
Three A+ grades at a top school (such as Kelley) are impressive.
I think that you are doing very well. I think that you should stay where you are, work very hard, keep ahead in your classes, and do as well as you can.
You will probably want some work experience before applying for your MBA.
