Begin to actively gather information on colleges that may interest you. As you study this information, compare yourself to the profile of the "average" student that a particular college or university accepts. Some websites that may prove helpful to you in your search are www.princetonreview.com, www.collegeview.com, and erudera.com.
Remember that for the determined student who is willing to work hard, there are always options to continue your education. Community college and junior college programs provide many students with excellent educational opportunities and often serve as bridges to four-year college programs. You are the key to your success.
