Sending application in two parts?

<p>My common app is almost done- it just needs the essays and the forms needed to be filled out by my counselor. But at my school the counselor fills out their part last and then they send it to the college with the application completed. </p>

<p>My question: could I send in the common app w/o the essays, but with the counselor forms and teacher recs separately from the NU supp and the common app essays? or do the common app need to be mailed in altogether?</p>
