CHECKLIST before you leave home tomorrow...

Check if you have the following:

1. Your Confirmation Slip / Entry Proof
2. Your I/C OR EZ-Link Card OR Student Pass
3. Your School Badge [seriously. This may seem redundant, but unless you want to waste time buying a badge before the paper begins, then you MUST have your badge on before and during the paper.]
4. Your Dictionary for Paper 1. Make sure that it is one of the MOE-approved dictionaries. [PDF link]. Note that there are two Chinese Electronic dictionaries which have been approved for use during the 'O' Levels, namely the HansVision Handheld Dictionary Model PX2051 and the Besta All Pass 1 Computerized Dictionary.
5. Also, make sure that you have the necessary stationaries. Pens, Ruler, pencil, etc. No correctional fluid / tape [well, you probably can use it as Yi Lei did last year, but it's not recommended, so don't]. No slips / pieces of paper. No nonsense.
6. FOR GOODNESS SAKE, MAKE SURE YOUR HANDPHONES ARE OFF OR REALLY IN SILENT MODE WITHOUT VIBRATION. unless you want a 'T' for this exam.

All the best!
