uhm to skip to the orgo section u would have to skip through all 30 gen chem questions then when ur finished skip back 30 places to get back to GC, thats not such a good idea--very time consuming cuz i can tell u no other 4.5 hrs goes as fast as those! I was allowed to touch the screens, it depends on the center u go to. My center was also really hi-tech, flat screen computers and all.
