SBA Q7 3E: Lists Start date and # of students enrolled in August of each year

in August of each year. Output should be ordered by start date ascending.

SELECT startDate, count(distinct studentId) 
FROM studentCourse
WHERE MONTH(startdate) ='08'
GROUP BY startdate
ORDER BY startdate, count(studentId);
