I tried to solve this problem using a WITH clause. I understand that the question is seeking an IN clause solution. However, I want to know if my answer would work and if not, why. Many thanks for any guidance. Both inputs follow:

My attempt
WITH math_and_english AS (
SELECT first_name, last_name
FROM math_students
INNER JOIN english_students
ON math_students.student_id = english_students.student_id
)
SELECT * FROM math_and_english;

Codecademy Solution
SELECT *
FROM math_students
WHERE student_id IN (
SELECT student_id
FROM english_students
);
