Can somebody help me correct these sentences?

1) The final exam will be 10%, so how does the teacher calculate the 10%?
2) The final exam is 10%, so how will the 10% be determined/computed/judge?

Ten percent of what?
Before correcting the sentences, we must know exactly what you want them to mean.

Some shots:
The final exam weight will be 10%.
The final exam contributes with 10% to the final note.
The final exam weights 10% but how should one calculate the final average?

Not a native speaker

The final exam contributes with 10% to the final note.

final mark you mean?

I agree that percentage is relative. It is meaningless to say 10% without any reference to sometime else.
