Hi,
I have a table of grades like this:
title, section, instructor, letter_grade, number_grade, uid
With data that would look like this:
English, 1, Smith, B, 88, 1
English, 1, Smith, B, 86, 1
English, 1, Smith, B+, 89, 1
Math, 1, Jones, A, 95, 2
Math, 1, Jones, B, 85, 2
Math, 2, Smith, C, 75, 3
Something like
SELECT uid,
AVG(number_grade) AS average_grade,
SUM(IF(letter_grade = 'A', 1, 0)) AS A_count,
SUM(IF(letter_grade = 'B+', 1, 0)) AS B+_count,
SUM(IF(letter_grade = 'B', 1, 0)) AS B_count,
SUM(IF(letter_grade = 'B-', 1, 0)) AS
