Is this form neccessary? Application for Temporary Resident Visa [IMM - 5257]

[zat]

Hey guys,

I am soon going to be filing for my visa soon and last time I did not submit the
Schedule 1 – Application for Temporary Resident Visa [IMM 5257 – Schedule 1] form as my agent said it was not necessary.

Is this form necessary? who does this form apply to?

I am applying under University category.

And

there seems to be two different sets of forms?
