Explanation:

The correct sentences would be: Graduation from high school and, of course, admission to a college—is a requirement for all recipients of the Chandler Memorial Scholarship.

The first dash, which is called En dash, is incorrect because we use En dashes when we want to mention a period of numbers or the relation between two words, for example, we can say:

The teacher told us to read from pages 10-20.

The second dash is an Em dash, which is correct because it is replacing a comma. We use Em dashes to avoid the excessive use of commas in a sentence.
