Find minimum datetime while using FK in two different tables

Question

I have 2 tables:

COURSE
------
Id
Name

TEST
------
Id
CourseId (FK to `COURSE.ID`)
DATETIME
NUMBERS

Suppose COURSE table with ID 1,2 (only 2 columns) and TEST table with 8 numbers of data having different DATETIME and CourseId of 1 (3 columns) and 2 (6 columns).

I want to find the minimum DATETIME,CourseID and Name by joining these 2 tables. The below query is giving a 2 output:

(SELECT  min([DATETIME]) as DATETIME ,[TEST].CourseID,Name
    FROM [dbo].[TEST]
    left JOIN [dbo].[COURSE]
    ON [dbo].[TEST].CourseID=[COURSE].ID GROUP BY CourseID,Name)

 

 I want single output i.e. a single output column (minimum datetime along with Name and ID)..HOW can i achieve??

 

With 2 courses i  always get 2 rows when joining like this. It will give me the minimum date value for each course. 

 

so any suggestion?
