Pulling MAX ID query pulls to many returns

I have a query that shows me the information on students we serve. The query pulls all of their classes and the status results as well as contact information. I need to query down to the LAST class taken and the students status. If I take out the following fields I get the correct return but I have to have all the information

"dbo.Class.Year, dbo.ClassResult.ClassResultStatusID, dbo.Class.SemesterID, dbo.Location.LocationName, dbo.Institution.InstName"*

                    
SELECT   MAX(dbo.ClassResult.ClassID)AS LASTCLASS,                    
            dbo.Person.PersonID,                    
            dbo.Person.LastName,
