Sometimes, some students go through evaluations different to those of the rest of their classmates. For this reason, you can overwrite a calculated formula and thus easily adapt the evaluation for a student in particular.
You only have to click on the cell with the right button of the mouse and select the Overwrite formula option.
Once you have clicked on this option, you will be able to modify the formula for a specific student. By clicking on the OK option, the changes will be saved.
If you press the Delete button, you will be able to delete the specific formula for the student and restore the original formula.
