Do I need to do a MPN and a Entrance Counseling for both Perkins and Stafford Loan?

<p>I just finished signing the Master Promissory Note for Stafford/Federal Direct Loan on <a href="https://dlenote.ed.gov/empn/index.jsp%5B/url%5D"&gt;https://dlenote.ed.gov/empn/index.jsp&lt;/a> and an Entrance Counseling on <a href="https://www.dl.ed.gov/borrower/BorrowerWelcomePage.jsp%5B/url%5D"&gt;https://www.dl.ed.gov/borrower/BorrowerWelcomePage.jsp&lt;/a>
Now I'm starting on the paper work for my Perkins loan and it says I also need to complete a MPN (<a href="https://www.acs-education.com/CS/Jsp/cpsesign/welcome.jsp%5B/url%5D"&gt;https://www.acs-education.com/CS/Jsp/cpsesign/welcome.jsp&lt;/a&gt;) as well as a Entrance Interview (Welcome</a> to Financial Counselor(TM))
I remember from the tutorial for Federal Direct Loan that I only need to sign one Master Promissory Note. Should I proceed with the MPN and interview for Perkins Loan?</p>
