What is your question?  What are you trying to accomplish?

Quick note: that table structure looks denormalized...

tblCourse(CourseID, CourseName, --) when CourseID is primary key
tblStudent(StudentID, FamilyName, ..) when StudentID is primary key
tblCourseStudent(CourseID, StudentID, ...) when CourseID and StudentID are foreign key
something like I do in transact sql code?

my question is, as it resolves a many to many relationship in transact sql code?
Your last table needs to look like this:

CrsStuID - primary key - autonumber
CourseID - foreign key from tblCourses
StudentID - foreign key from tblStudents
PerformanceMetric1 - datatype as required
PerformanceMetric2 - datatype as required

I always pluralize tables - it is so much more natural - notwithstanding some pundits!  tblStudent sounds like info about only one student.

There is no code to form the third table.  You should create a form with combo boxes for both Courses and Students as well as some way of entering all the performance metrics (combo or list box)
	tblCourse C
	tblCourseStudent CS ON C.CourseID = CS.CourseID
	tblStudent S ON CS.StudentID = CS.StudentID

tblCoursesStudents is the Joining table between the two Many to Many tables allowing a one-to-many

tblCourses M-----> tblCoursesStudents <------M tblStudents

tblCourses and tblStudents are an eschema Intranet, these tables already exist. The new table is tblCoursesStudents,  therefore would only have to make the code table creating tblCoursesStudents or I do something extra in the tables tblCourses and tblStudents
Somehow you have to get the info about what students are taking what course into the the tblCoursesStudents.  As I suggested earlier, the best way would be to use a form designed for that purpose.  You have to create the table and then use the form to populate it.
