Good Luck I'm sure the date won't influence your exams ... You know, many of people consider themselves unlucky today, so there is lack of badluck (as everybody counting with it today) and much unused luck , so take some luck from the pool and pass them with A+ (or atleast pass )
http://en.wikipedia.org/wiki/Friday_the_13th Friday the 13th is considered a day of bad luck in English-, French- and Portuguese-speaking countries around the world, as well as in Austria, Germany, Estonia, Finland, The Netherlands, Belgium, Republic of Ireland, Poland, Bulgaria, Denmark, Iceland, Sweden, Norway, Czech Republic, Slovakia, Slovenia, Hungary, and the Philippines.
In my life so many of friday 13th came and gone away but never faced anything bad.... I am sure nothing will happen today also because its all crap nothing else...
So far so good, not a bad day, just hope all this negative energy running around the world doesn't come round and bite me
