College Confidential is a great site for those researching various schools or interested different programs of study. It is a great expansion and addition to any of the research you do from my site. I hang out in the finance and graduate business forums so if you are researching a masters in finance program odds are our paths will cross.
In addition to reading other students questions the website also gives you the ability to see applicants profiles. Very handy when you are trying to assess your own chances of being admitted to the programs that you are applying to.
You can also research other masters programs, such as the masters in accounting or the masters in management. It also lets you research the other aspects of college besides just the degree program. This is just as important as learning about placements and class profiles.
