# Office Hours and Advising with Al Evangelista

> Feel free to sign up any 15-min or 30-min slot. Do not sign up for more than 30 minutes, unless we’ve discussed it previously. Only available time slots are shown. If it looks like there are missing times, it is because someone has already signed up during that slot. Do not sign up for a time that conflicts with your other class meetings or obligations. If the only times available are times you have class or meetings, email me with at least two times and dates you are available the week in question, and we’ll make an appointment. I'm looking forward to talking to you!
