I think it depends on the college you are going to. Some of my buddies actually got credit for a class or two because of certs they had. He only got credit for them which, obviously doesnt improve or hurt his gpa. You may want to ask your advisor that question. I'm sure exceptions can always be made.
Are you already in college? Have you declared a major yet? If so, do you have a general counselor that was assigned to you or do you have one that is specifically in the I/S dept?
Does having certain certs like A+ or Net+ can exempt you from having to take a certain class in a college or university?
My particular school has several classes that track to specific certifications as part of the Computer Information Systems curriculum. The teacher that does almost all the networking classes will give you an "A" in the course if you pass the corresponding exam before the end of the semester your'e enrolled in the class. Of course, he's also willing to give you the grade if you bring proof that you already have done the test, since his logic is that, if you've passed the certification exam, then you've probably already learned just about everything the class has to offer.
Here is an example of what the community college I attended does: http://www.ccac.edu/default.aspx?id=138905
At the time I enrolled, they also accepted NT exams. A lot of the courses had a lot of overlap with specific certifications.
When i took my Networking Concepts class, the instructor had said on the first day that anyone who took and passed (or already had0 the Network+ certification would receive an instant A in the class and would no long have to attend the class. So, while the college sometimes may not budge on the issue, the instructor for a specific class might.
