Hi.... Koreas unique ability makes it suitable for all victory types, but particularly the science victory. If playing as Korea, you will
definitely be and era ahead of others if used properly
My path to science victory:
1)First rush 'writing' tech in order to get access to the great library. Start building The Great Library.
2)Next tech to research is 'philosophy'. Done that then you get access to the national college.
3)Rush 'education' tech to get access to university and oxford university.
4)Research 'scientific theory' next. Done that then you can build a public school.
5)Rush 'future tech' to get everything else.
6)Start apollo programme once available.
Social Policies

in order of adopting)
Tradition--> Aristocracy-> Legalism-> Landed elite-> Liberty--> Republic-> Collective Rule-> Citizenship-> Monarchy-> Rationalism-->
any other policies
Things to note:
While rushing 'education', this will be your best time to build up your early defence and improving you civ.
Have a maximum of 2-3 cities and grow them to a size of 10 at least.
Build more defensive units than offensive (with some ranged ones).
Level up your first spy, then move him to your capital.
Maintain your happiness, it helps generate science.
