Chances for next year?

I’m a junior in NOVA. My stats are:

3.9 wGPA (Should be better next year, likely 4.05/4.1)
29 ACT (Retaking)
Lots of ECs, but those will take a while to type out. I’m very well qualified in ECs.

How likely am I to get in? I hope to do the IA major.

Do some research on the IA major. You can’t even take any of the major related classes until fall of your sophomore year. You qualify for the major based on your performance in 3 specific 200 level classes + a 200 level math class.

I don’t know how applying as an IA major might effect your chances.

You can always declare IA at orientation or early on in your freshman year.
