In most events, you don't have to win the tournament to win a prize -- you can win a class prize as a top scorer of your rating group, or a section prize in a section restricted to your rating group. The ratings groups are:

2400+up Senior Master           1000-1199 Class E
2200-2399 Master                    800- 999 Class F

1400-1599 Class C                   100- 199 Class J
1200-1399 Class D

Some tournaments use different groups such as 1900-2099, and some have "under" prizes or sections that are limited to players below a certain rating.
