since the card info is there, they will just charge the correct amount. In my case, i put the wrong amount down. I read the fee as PAL=$60. RPAL=$80 and thus i put $140 down. I figured since there were two separate courses and tests. There would be a separate fee for each and not 60 for pal and 80 for combined pal+rpal.
there was no delay in my application. They just charged the 80. (app received March 21 2019 - CC charged April 11 2019)
