<p>Do colleges have a preference of what type of envelope is used to send in the rec's and evaluation forms?</p>
<p>The only school that I ever heard do that is Stanford - 9x12. Though I suspect most schools would prefer if you did it online.</p>
<p>how about fee waivers?</p>
<p>really - the only way you are going to know this is to check the instructions for each school you are applying to.</p>
