CREATE TABLE CLASS (class_code VARCHAR, crs_code VARCHAR)
CREATE TABLE student (stu_gpa INT, stu_num VARCHAR)
CREATE TABLE enroll (stu_num VARCHAR, class_code VARCHAR)

What is the average gpa of the students enrolled in the course with code ACCT-211?
SELECT AVG(T2.stu_gpa) FROM enroll AS T1 JOIN student AS T2 ON T1.stu_num = T2.stu_num JOIN CLASS AS T3 ON T1.class_code = T3.class_code WHERE T3.crs_code = 'ACCT-211'
SELECT AVG("T2"."stu_gpa") FROM "enroll" AS "T1" JOIN "student" AS "T2" ON "T1"."stu_num" = "T2"."stu_num" JOIN "CLASS" AS "T3" ON "T1"."class_code" = "T3"."class_code" AND "T3"."crs_code" = 'ACCT-211'
