If you're still unsure about classes, take a look at some of these steadfast courses that are popular year after year. Although they may not be the easiest, without fail, these classes consistently fill up lecture halls. Of course, some of these courses are so popular that they've already been lotteried...so keep these in mind for next year as well.
Some people smugly tell you, the day before classes even start, that they know exactly what they're taking. Others, on the eve of study card day, admit that they don't have a clue—either hanging harried heads in shame, or speaking with great pride in their indecision (like this blogger, who once happily printed six different versions of her study card for her adviser to sign).
Some students scribble notes throughout the first lecture; some don't even bring a book bag. Some are sitting in their seats on the first day perfectly on time and would never dream of cutting out early, while others crowd in long after all the chairs are taken, or awkwardly climb over dozens of fellow shoppers to leave before the lecture ends.
Shopping week, derided by some as stressful and hailed by many more as an exhilarating opportunity to sample the mind-boggling variety of courses offered at Harvard, can be a very personal matter. One of those choices that all shoppers must make is their shopping tool.
Just as shopping week offers you far more courses than you can take, the menu of shopping tools available to you is broad, and you have to pick. Don't get caught with part of your shopping list in one place and part in another, then realize at the last minute that you have a schedule conflict you didn't notice because one course was on your my.harvard list and the other was stored by CS50.
