how late is too late?

<p>I've been very finicky with my schedule so far and have been undecided on my last course to take. I've attended two classes that I did not like so far, so I decided to drop them. Now we're in the third week and I just registered for a upper division history class which meets twice a week, translated means I've missed the first 4 classes. Do you guys think it's too late to be adding this late? Did I miss too much to recover? thanks</p>

<p>I think it would be better if you simply ask the instructor, preferably face-to-face.</p>
