Academic Points
When Klaus arrived at the main campus building, which was the reception building and the big building where he did all the stages of the selection process, he noticed that the place was much busier than the rest of the campus.
He had the impression that there were at least a few hundred people on the first floor of that building alone, talking to teachers, talking to each other, and even waiting for other people.
Since Klaus wanted to ask some questions about something he had read in the e-mail from NIST, he thought it would be good to talk to an instructor first to get some answers before deciding whether or not to go to a lecture that would go into the subject in more depth. And since this particular program experience was new not only to him but to all the students, there were many people confused and curious about various things, so the lines to talk to the instructors were long.
