Common Mistakes

Using a case value that does not match the variable, so the default case runs.

The case for number 3 should be '3' to match the variable value and print "Three".

Using a weekday instead of Sunday in the case.

The case should include "Sunday" along with "Saturday" to print "Weekend" for both days.

Common Mistakes

Trying to match multiple characters in one case using a string or list.

Each case must match a single value. To check multiple vowels, multiple cases or a where clause is needed. Here, only 'a' is handled.

Using overlapping or incorrect ranges causing wrong category.

Scores 0-49 fail, 50-79 pass, 80-100 excellent. The ranges match these categories.
