my skool was was the same , my group felt we did better in the trials then the real thing. we had an open showcase nite and did our performances, which were our trial marks. the audience were our friends and family and they LOVED IT! out group got between 84 and 91% (we were all marked separately)
our school was on the FIRST day, the audience was SOOO nervous for us and so we couldn't "feed off them" as much as we could. plus, most of the jokes went straigh over their heads cause they were too young.
still, my IP was 1000 times betta on the day, as my trial was a DISASTER!
GOOD LUCK TO EVERYONE FOR THE 1st of Nov!!! peace out!
