How to select students that failed at least at all courses that student with id = 1 failed?

I have the following tables: STUDENT (student_id, first_name, last_name, birth_date, year , domain) PROFESSOR (professor_id, first_name, last_name, birth_date, hire_date, title, salary) COURSE (course_id, course_name, professor_id) GRADE (student_id, course_id, grade, date_of_exam) I have to display the students that failed at least at all the courses that student with id = 1 failed. What I tried: SELECT s.student_id, s.first_name, s.last_name, n.grade, n.course_id FROM student s JOIN grade n ON n.student_id = s.student_id WHERE n.grade <= 4; ...this gets all the students that failed but I don't know how to go from this to all the students that failed at least at all the courses that student with id = 1 failed. If someone could point me in the right direction I would be grateful! **Additional details** For example: If student with id = 1 failed at courses with ids = 2,3. And we have other two students who failed at courses with ids = 2,3 (like student 1) and they might fail at other courses too, then I want to display those two students.
