Here an example how you can query in the form you want:

XDocument doc = XDocument.Load("test.xml");
var query = from l in doc.Descendants("L1")
            let id = l.Attribute("id").Value
            from subject in l.Descendants("Subject")
            select new
            {
                Id = id,
                SubjectName = (string)subject.Attribute("SubjectName"),
                Score = (string)subject.Attribute("Score")
            };

foreach (var result in query)
{
    Console.WriteLine(result);
}

Output:

{ Id = 10, SubjectName = Subject1, Score = A1 }
{ Id = 10, SubjectName = Subject2, Score = B1 }
{ Id = 10, SubjectName = Subject3, Score = C1 }
{ Id = 20, SubjectName = Subject1, Score = B2 }
{ Id = 20, SubjectName = Subject2, Score = A1 }
{ Id = 20, SubjectName = Subject3, Score = C2 }
