Does dropping out of high school affect college admission?

There won't be (mainly depending on your college entrance examination scores)

It doesn't matter if you resign. It's not like we're clinging to party member in the 1970s and 1980s! In fact, League members and party member are just a form, just like the Young Pioneers in primary schools. Besides, whether you quit the party or not has nothing to do with studying abroad or emigrating.
