need help with a query

[Jabba]

How would I get the average grade of each student?


table name = grade
+---+---------+
| student | grade |
+---+---------+
| john | 85 |
+---+---------+
| jeff | 90 |
+---+---------+
| jenny | 85 |
+---+---------+
| jeff | 88 |
+---+---------+
| john | 89 |
+---+---------+
| jenny | 82 |
+---+---------+

select student, avg(grade) average_grade
from grade
group by student;
