Cyclomatic Complexity of Nested Conditionals

The following code segment uses a nested conditional structure to determine a student’s academic status.

IF (credits >= 90)
IF (gpa >= 2.0)
status = “Senior in good standing”
ELSE
status = “Senior on probation”
ELSE IF (credits >= 60)
IF (gpa >= 2.0)
status = “Junior in good standing”
ELSE
status = “Junior on probation”

What is the cyclomatic complexity of this code segment?
