저기요 there... everyone!!!

i'm atheist ....

Cool story bro, tell it again.

Uhh..

okay. :-)

ok,i don't know your name but i will just say "that person from fanpop-xebbi" :)

Okaayyy!.... (: i have, good luck hon!

Praying 4 ya already.
Even though im not that religious, God Bless 당신 :)

Good luck I know that 당신 will do well. Just do your best and don't worry about a thing.

Okay I did! :) :D :p

I'll send 당신 good energy! :DDD Good luck!

And if I'm not religious, then what do I do?

Well i could pray to the Goddess to favour 당신 in your time of need, but 당신 could also wear 호랑이 Eye which will give 당신 the confidence to excel in your examinations and also focus your mind and brain activity to study and work hard.
당신 could also do the good luck candle charm.
It's quite simple and cost effective.
all 당신 need is
1. white candle (your mother should have one of these, if not 당신 can buy one really cheaply at markets)
2. one blue ribbon any size as long as it can fit the candle width
3. piece of paper and a pen
4. one bowl of water and an empty bowl
5. belief XD (i added this bit LOL)

okay here's what 당신 do.
1. place the candle in-between both bowls (the one full of water to the left, the empty one to the right)
2. 덮개, 랩 the blue ribbon around the base of the candle (this is the safest option, if 당신 덮개, 랩 the ribbon around the candle from wick to base like some say 당신 could end up burning the ribbon and causing a fire)
3. Write on the paper and the pen your ambitions (in this case to do well in your exams and possibly as to where the grades will lead you)
4. Fold the paper in two, dip in the bowl of water and say "Goddess of Moon, God of Sun, Goddess of Earth, God of fire, i call to 당신 to grant me this wish. I wish (and name what 당신 have written).
5. Swipe the wet paper above the candle flame until it catches 불, 화재 and place in the empty bowl. Repeat your wish until the 불, 화재 goes out.
6. Repeat daily (meaning new bowl of water and retying the ribbon over the candle (no need for new candle 또는 ribbon) until your exams)
7. Not necessary but could give a boost - cut a tiny amount of your hair, ties it in a white ribbon and say "Goddess, i give this self-sacrifice in your favour, in your honour. I wish 당신 to grant me (name what is on your paper). Repeat step 5 and add your sacrificed hair and ribbon to the mix.

Please be careful when using candles and fire, remember to always snuff the candle when going to 침대 또는 out and never leave a candle on it's own to burn. Always keep another bowl of water 또는 a wet tea-cloth at hand just in case of accidents.
