Letters of Recommendation for transfer to Purdue

<p>Hey there,</p>

<p>I'm applying as a transfer to Purdue, and I'm wondering if I should send letters of recommendation. They're not required, but would they help or make a difference at all? I've got a 4.0 GPA (community college), and I'm looking to transfer into the biology program as a junior, if that matters. Thanks in advance for any replies! :)</p>
