Replying to Will this be a problem?

This friday is my road test and I will be driving a '98 camry. The check engine light is on and it has been for a while. I'm pretty sure it just needs a new O2 sensor and I just haven't got around to getting that checked out because its not really my car yet. The car runs fine, not one problem. I'm just feeling like theyre going to say they can't perform the test because the check engine light is on or some bullshit. Will I still be able to take my road test? I think i'll be fine but i'm just over thinking it because I really want my license.
