The conditional approval letter can be accessed by clicking on the link in GOES and then selecting print. Your "message inbox" on the site should show a conditional approval notification and on the right you will see a blue button that says "read notification." Once clicked, you can then print.

I submitted on 5/13 after, was conditionally approved on 5/19, original appointment at Dulles Airport was 6/27, then after some refreshes I picked up 6/17. Then I got serious and did some reading and figured out how to make my computer "watch" the calendar for May and alert me when there was a change. Last Saturday an opening came up for 1:15 today (5/24) and I'm about to leave now for my appointment
