You know how 私 can mean private and how 大 is the first half of 大学? Well, combine those together and you have the shortened version of private college or private university.
しだい
This is a jukugo word, which usually means on'yomi readings from the kanji. Since 大 has two on'yomi readings, here's a mnemonic to help you remember which one to use: You went to a specific private college just to study dyes (だい).
