School's event, Clue hunting

Almost all of the school students had gathered in Hall. There were many wooden chairs placed in hall that were facing to stage that was at other side of hall from door. Everybody had picked a seat in a row depending on their grade. There were kids from twelfth grade, from fifth and even from first, all grades could participate.
The teachers were at that time in corner of stage appearing to be discussing something in quiet. Nobody could really hear that since the hall was loud from all the talking. Even though nobody here was talking loud, but in a pretty normal voice, all together ended up loud.

Some of teachers were current getting the clues ready and lists.
Everyone who would enter the hall, a teacher would speak to them: "Please take a seat!"

Alex came in and took a seat next to George, Amy, and Mitch.

Kari went inside the hall and was quite amazed by the number of students inside. Remembering she was just standing there, Kari immediately took a seat in the front and plugged her ears cause the noise was bothering her a bit.

Soon enough the teachers stopped talking and the teachers scattered to walls of hall standing with gallant stance waiting for the director's secretary to begin speaking. The secretary went up on stage holding a microphone, she was pretty tall and had long red hair. "Welcome all students to the first school's clue hunting event!" she said while the voice came out of Speakers in stage's corners. At that moment almost all students stopped talking and started paying attention to the secretary. The speakers were loud enough for everyone to hear, but not too loud.

"The winner of this event will be the student that will collect most pins, which are hidden all around the school.
The pins are unique and one of a kind each having a certain number on it, if the number on pin matches the number of your riddle, then it's the correct one and you can take it. The students that arrive at wrong classroom, instructor, which will be the teacher of that class, will not give you a pin.

First, you will each receive a paper with list of riddles or clues that you will need to unlock answer from and go to that certain cabinet, where they will meet a teacher and the teacher will give them the pin if it's correct.

Remember, you can go in any order you want, so if your stuck at a certain riddle or clue, just move onto next one.

So, are you all ready?"

Alex walked up to Nayden "Nayden, wanna work toghether?" He asked.

((Um... Just a quick note the name tag doesn't say Kari, it says Nayden. Nayden changed her name to Kari so she wouldn't be figured out))

(Bottom line - Read the rules. It says you must be realistic and can't ignore one's defenses. I corrected Alex's post. Kari's turn to post post)

Nayden was a bit startled by the request but after thinking about it for awhile, she nodded.

Just at the time a teacher was passing by and stopped at the kids after hearing them speak. She bent a bit over to both of them with a smile and kind voice. "I'm sorry, but this event can only be done individually." after that, she stood up and walked away to continue to do her business.

Biggest part of students sitting shouted: 'Ready!' after the secretary asked if they were. The secretary then smiled continuing: "Alright, all participants please walk over to the desk" she pointed to it which was just below the stage, "sign your name, class and get your envelope that will contain the list with things you need to do. But don't open it till we allow."

bump =.=

Alex walked over to the desk. "Alex Jones." He said his name.

(Kari1412's post skipped)

The assistant (who was a senior student that was requested to help with the event) at desk wrote down Alex's name in first column from three column table. Taking a paper with clues 1 to 10, the assistant also wrote down Alex's questions in second column, third column will be to write down how many clues solved after the event. "Here you go, Alex!" the assistant gave Alex the paper with question.
"Next please!"
