As-level exam

I've just finished my As-level exam lately.
Let me tell you what I saw and experienced during the exam days, and some important things about this exam.
This is an international examination. 
Two things every candidates must bring along to the exam hall:

• The statement of entry, which includes the important details of a candidate, the subjects that a candidate is taking and the date of exams.
• Student ID, which is a proof that the candidate is a student of that particular college

Things that candidates are not allowed to bring :

• Stationary with stickers or price tags
• Erasers with wordings on it
• Water bottle that is not totally transparent and colourless

The first place where a candidate should go before an exam starts is the storage room. Students should put their bags and belongings there before entering the exam hall.
Usually people would do their last minute discussions with their friends in the storage room to make sure that they didn't miss out any important thing to to study. Some students wouldn't leave their books until the last minute before leaving the storage room.
Oh ya, every candidate has their very own candidate number, they would have to check their seat positions at the plan diagram before taking their seats in the exam hall.

All the desks in the exam halls were blue and made of plastics. There are around 12 air-conditionals in the hall.
The exam hall was really not bad and it has really provided an excellent condition for every candidate to do their exams. Instructions given by the invigilators were very clear. Everything is extremely formal when you're in the exam hall. "You are now under exam condition." This is the first sentence that an invigilator would say once we had all taken our seats. All exam question papers came in closed packages. Several invigilators would cut open the packages in front of all candidates, and this looked really formal. The papers are then distributed to everybody. When the exam ends, the question papers would be collected with the answer sheets as well. Candidates would be allowed to leave the hall after the invigilators had kept all the exam papers well in a box.
