so flipping mad

ok so today at clinicals our instructor gives us our assignments and I was not paired up with anyone and had a pt to do...no biggie. Well another lady was also by herself and had a pt. Well she had never worked in a facility before and was nervous. So the instructor paired us up....................BUT LEFT US WITH BOTH PTS. Not cool. All the other pairs had 1 patient to do...............so we start on her patient and were told that we needed to do mine 1st per occupational therapy needed him. So in order to get marked off on items we do we need the instructor to watch us, so basically it takes FOREVER. So being as the instructor has to see everything we do it took almost 1 hour to get him done.............meanwhile per family instructions the other patient had to be gotten up by staff....she was already done when we were ready for her......................our instructor marked us as having an incomplete assignment due to the fact she may have staffed inapproprately................OMG I could have killed her
