Length of time for paper check to clear?

<p>Have any other parents had the misfortune of mailing a paper check for tuition/fees/housing to Cal? I know online bank transfer is immediate and infinitely easier, but a relative of the kid is kicking in, and mailed a paper check straight to the university. Tried to warn her...ouch! Three weeks later, nada. No reflection on the CARS account. Went through this when we mailed a paper scholarship check too. I know it just takes forever, but does anyone know exactly how long forever is? Any clue why? Thanks!</p>
