Going to the Witchcarft school was easier than he thought ...
When he reached there and wanted to enroll ,the guards outside noticed him and allowed him in ...
it seems that the Dean of the shapshifting academy informed the headmistress of the witchcraft academy about his arrival ...
Reaching there , he was instantly accepted and started learning witchcraft the next day , after getting a new dorm room and school supplies of course ...
Witchcraft is a deep art with profound knowledge ...
it has various branches , but the main ones are :-
* Fortune Telling : done through various methods like watching the stars ,reading the palm lines or face lines , Xylomancy using numbers , predicting through calculations ,... etc
* Curses : Self-explanatory ,they can curse their enemies or items with powerful curses
* Runecraft : they can inscribe mystical runes onto items to make them have magical effects
* Summoning : they can summon devils ,ghosts or dead people from the netherworld to do their wishes
* Contracts : they can make contracts with other people or devil's with some conditions of both parties
* Potions : they can create magical potions by mixing various magical things & herbs , and using a unique method
* Mind Arts : They can use Telepathy & Mind Reading & Hypnosis & Illusions ... they can also enslave the will of others (like babidi)
Oolong chose to go to the witchcraft school first before the magic school because he thought it was easier ...
Well ,in reality ,it may even be harder with all its various profound branches ...
After spending a year and half at the shapeshifting academy ,he is already more than 6 years old now ...
he had some plans for himself ,to get benefits from the plot to the maximum ...
Oolong is three years younger than goku ...
when goku started his journey with bulma , he was 12 years old ...
That means that Oolong will be 9 years old by that time...
which means , he only has less than 3 years before the start of series ...
he planned to make the best use of this period of time so he can achieve his goals when he meets the group of main characters ...
Something to note is that Oolong never gave up on the training the he began since he was a child ...
he was always trying to improve in his mental calculation method , doing multiple things at the same time and training his body ...
In the dragonball world ,the more stress you feel and the harder you train ,the more you improve ...
and since he knows about zeno-sama ,the stress on him is quite big , which pushes him to improve and push his limits ...
In this way ,He continued learning & training ,pushing himself to do his best at everything and improve constantly ,so that he can fulfil his plans & achieve his dreams !!!
and like this ,another year passed quickly , and Oolong already masters Witchcraft ...

{{{{{{ Note // that is my own theory ... just look at goku between the time of defeating new piccolo to the time of saipan invasion ,and you'll know the difference ....
Goku spent several years with no major improvement in his strength , but when he knew that there are people stronger than him ,he reached incredible heights ....
in just one year , he reached 8618 from about 400 ...
and had explosive growth till the time he fought frieze and reached a peak ....
then he stagnated till he knew about the androids ...
then stagnated but had an explosive growth against buu ...
then stagnated and grew again against beerus ....
you will notice a pattern here }}}}}
