Google Forms: Auto-update sheet from submitted responses

Question

Response are automatically added to the sheet "Form Responses". I want to apply certain formulas in a sheet called "Student Answers". However, "Student Answers" doesn't auto-update from the submitted responses. Here are the formulas I am trying to use:

='Form Responses'!A1 etc.
=IF('Form Responses'!E6='Answers'!$E$2,1,0) "Answers" is another sheet with an answer key
=SUM(D5:I5) this sums the numbers given in the previous formula.

Basically, I have created a quiz, and I want to grade the quiz on a separate sheet. Here is the Sheet in question.

Answer 1

The solution was to use =ARRAYFORMULA. Here are my working examples:

=ArrayFormula('Student Submissions'!A:C) for basic copying of columns

=ARRAYFORMULA(If('Student Submissions'!D3:D='Student Submissions'!D3,1,0)) for IF statements

=ArrayFormula(mmult(D3:I;TRANSPOSE(sign(column(D3:I))))) for SUM

=ARRAYFORMULA(J3:J/6*100) for AVERAGE and percent
