Application fee waiver question

<p>I got a question regarding the CSU and UC application fee waiver(not sure exactly where to put this so mod feel free to move it)</p>

<p>I know read that UC and CSU offer application fee waiver if you apply online and it cover up to 4 applications. But is the fee waiver the same for both of them, meaning do I get 4 fee waivers for UCs and another 4 for CSUs? And if I have attained 4 collegeboard fee waivers from my counselor can I mail them in instead of paying with a credit card?</p>
