Thanks to tyw acting troupe owner's contribution to the contest, but due to my strained relationship with tyw, tyw canceled all my cooperation with her. the CTFPC-3rd's question and publicity work were handed over to me, I'm alexander this time.
CTFPC-3RD Time: Around Mid-Autumn Festival, more specific time to be further notified after the start of the school year.
tyw first came up with the idea of coming up with the preliminary questions, and I finished coming up with the preliminary questions, so this time we actually have two divisions: a preliminary division and a repechage division, and we don't have a selection system thatAnyone who pays can participate.。
Because I was a little short on cash and the quality of the race was a quantum leap from the previous two, perfectly suited to the environment of the CCF series (This time using file read-in and read-out, the author's computer unified assessment), so give a little money.CCF's CSP-J preliminary round costs 50, and the final round costs more than 300. Our registration fee is very affordable, cheaper than a bus ride.. Here is the price list:
-

About Group Buying
