Question:

Why are some of the words and numbers in blue?

Answer:

Any text or number on the web page that is blue in color indicates that there is more data associated with that text (a window with additional data will open)
and clicking the blue text/number will allow you to dig deeper. By clicking on the blue links you can email teacher, view details of student’s attendance, view all academic exam results and assignments for a student, and view student discipline.
