Subqueries as Table 1 practice problem

Screen Link:

My Code:

SELECT performance.*, parental_edu_reading_avg
  FROM performance
SELECT student_id,parental_education,AVG(reading_score) as parental_edu_reading_avg
  FROM performance
 GROUP BY parental_education) as p
 ON performance.student_id=p.student_id

Ques- Write a query that joins the performance table to an aggregated table containing each of the reading_score averages among each parental_education category.

Expected the solution to work. But it is failing because of the join condition. I am unable to know why the join condition is wrong.
