What is the likelihood I will be rescinded from UNC?

I got into the honors program. I am in IB and I am taking all IB classes. My unweighted GPA after junior year was 3.91.
I am taking some really hard classes this year. This is what my end of the year grades will look like
IB 20th Century - B
IB English - B
AP Calc AB - B
IB Physics - B
IB Latin - A
IB Psychology - A

My grades have not dropped from the first semester. Most of them will get a little better. I am just sick of worrying. I have worked too hard to stress out about this and the last thing that I want is to be rescinded or to be kicked out of honors college because my course load is hard. Should I be stressed out? There is no possible way I can make them better than what I described. Do you think I will be rescinded from UNC or its honors college?

It is very unlikely you would be rescinded from UNC for a few Bs. I am not sure what their honors program policies are, but you could call admissions and ask.

The consensus is that "D"s could be a cause for worry, but a few senior year "B"s should be fine.
