CREATE TABLE track (Track_ID NUMBER, Name CLOB, Location CLOB, Seating FLOAT, Year_Opened FLOAT)
CREATE TABLE race (Race_ID NUMBER, Name CLOB, Class CLOB, Date CLOB, Track_ID CLOB)

Show the race class and number of races in each class, and could you rank Y-axis in desc order?
SELECT Class, COUNT(*) FROM race GROUP BY Class ORDER BY COUNT(*) DESC
SELECT "Class", COUNT(*) FROM "race" GROUP BY "Class" ORDER BY COUNT(*) DESC
