How do I know what courses to select in each semester?

To find out what courses are required for the specialization (major, minor, area of concentration) you have declared you should refer to your Student Planning module on WebAdvisor. To determine if there is a specific order which these courses should be taken you refer to the Schedule of Studies in Section X of the Undergraduate Calendar (or the Diploma Program Calendar if you are in an Associate Diploma Program). For this information use the Undergraduate Calendar for the year provided in your Student Planning module.
