build query from output data

We have one table Say ‘student’ with below structure:

S_id int null,
S_name varchar(100),
S_marks int null

Data is something like :

s_id subject s_marks
1 English 40
1 Spanish 45
1 German 50
2 Physics 60
2 Chemistry 65
2 Maths 70
3 Statistics 80
3 Economics 85

Write such a query so that I will get output as below

s_id subject s_marks
1 English 40
1 Spanish 45
1 German 50
1 NA NA
1 NA NA
