SQL Query Required

I have a table

Table1
------

StudentId Class Test1 Marks1 Test2 Marks2 Test3 Marks3
---------------------------------------------------------------------------
1 1 1 50 3 35 5 40
2 1 1 50 4 40 7 43
3 2 1 47 3 50 6 42


I would like to Insert this data into another table in this form

Table2
------

StudentId Test Marks
---------------------------
1 1 50
1 3 35
1 5 40
2 1 50
2 4 40
2 7 43
3 1 47
3 3 50
3 6 42


Can you write a SQL Query to accomplish this.

Thank you
