# 1112. Highest Grade For Each Student

https://leetcode.com/problems/highest-grade-for-each-student

## Description

Table: `Enrollments`

```
+---------------+---------+
| Column Name   | Type    |
+---------------+---------+
| student\_id    | int     |
| course\_id     | int     |
| grade         | int     |
+---------------+---------+
(student\_id, course\_id) is the primary key of this table.
```

Write a SQL query to find the highest grade with its corresponding course for each student. In case of a tie, you should find the course with the smallest `course_id`. The output must be sorted by increasing `student_id`.

The query result format is in the following example:

```
Enrollments table:
+------------+-------------------+
| student\_id | course\_id | grade |
+------------+-----------+-------+
| 2          | 2         | 95    |
| 2          | 3         | 95    |
| 1          | 1         | 90    |
| 1          | 2         | 99    |
| 3          | 1         | 80    |
| 3          | 2         | 75    |
| 3          | 3         | 82    |
+------------+-----------+-------+
Result table:
+------------+-------------------+
| student\_id | course\_id | grade |
+------------+-----------+-------+
| 1          | 2         | 99    |
| 2          | 2         | 95    |
| 3          | 3         | 82    |
+------------+-----------+-------+
```
