Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE enroll (stu_num VARCHAR, class_code VARCHAR)
TABLE: CREATE TABLE CLASS (class_code VARCHAR, crs_code VARCHAR)
TABLE: CREATE TABLE student (stu_fname VARCHAR, stu_num VARCHAR, stu_lname VARCHAR)

### Question ###
What is the first name of the student whose last name starting with the letter S and is taking ACCT-211 class?

### Accurate SQL ###

SELECT T1.stu_fname FROM student AS T1 JOIN enroll AS T2 ON T1.stu_num = T2.stu_num JOIN CLASS AS T3 ON T2.class_code = T3.class_code WHERE T3.crs_code = 'ACCT-211' AND T1.stu_lname LIKE 'S%'
