I've tried doing this before , not sure if it works for you guys
.
Primary School :
Acting sick
- Mainly sore eyes , you can get them easily , jus stare at one
object , open you eyes wides , don't blink , and you'll get them ,
most primary school teachers are convinced because ur a kid.

Secondary School :
You can't skive alot in secondary school , mainly in class
chit-chat n etc , alternate ways .
Going to the restrooms
- Best excuse , you can skive for like 1/2hr ? Thats if you aren't
marked by your teachers , but some schools gives like a toilet pass
, which makes it harder , this way works best with upper
secondary.
Gastric
- well it works with Primary school too if you say , but some don't
know where are they suspossed to feel the pain* , many make
themselves malu*. So mainly used in secondary school , Gastric can
be used whole time in school , in the morning , just say that you
haven't had breakfast and you feel pain , most likely your teachers
will allow you to go to the canteen , that's when you skive.Works
for me
.
JC n U etc:
well , for this you need lots of help from your friends ! So make
some good friends NOW ! Hahax. Don't make enemies
PONTANG
- Okay , the lecturers mostly take a WHOLE bunch of students , he
won't know if you are missing , well of course unless you sit
infront . Best is that you sit beside the door.When the lesson is
almost ended, sneak back in . Its actually quite simple.

Well , i hope this helps abit , but your brains are active , many
people are constantly thinking of many ideas on how to skive aka
pontang [ ponteng ].
THE STRONGEST SURVIVES ! Old tactics are useless nowdays 
Just remember , you will be the winner , for today , tomorrow and
forever
Cheers!
