Help with simple mysql query please

Hello,
I have a mysql table called Points with like :

Name | Grade | Points
Bill | 1 | 5
Tom | 1 | 10
Fred | 2 | 7
Amy | 2 | 3
Ally | 3 | 10
Zoe | 3 | 11
and so on......

I need a query that will return the top point leader by grade.
1 - Tom - 10
2 - Fred - 7
3 - Zoe = 11

Can someone tell me how to do this?

What's your requirement when multiple 'name' end up in first place for a
grade?

You are looking for the strawberry query.
http://dev.mysql.com/doc/refman/5.0/...group-row.html
Look at the LEFT JOIN example (NOT the subselect)

Using the above link I used ...

select Name,Grade,points from Test1 t1
where points = (select max(points) from Test1 t2
where t1.Grade = t2.Grade)
order by Grade
;

Wrong one!!!!

The section itself (as did I) points out that the correct one to use is the
LEFT JOIN. It is far more efficient!
