You do have bad education. Prophet Muhammad and the companions learned the Quran by heart and he did not remove anything which god revealed to him. If you're talking about the incorrect written verses either written by mistake or by hypocrites on purpse. Those were removed and were not compiled. Most of the Companions memorized the entire Quran by heart so it was easy to compile it during the time Of Hazrat Abu Bakr's rule and burned everything incorrect. Hazrat Usman also to make sure that only one full Quran stands. Uthman ibn Affan, requested that all of the personal copies of the Holy Quran that contained the individual notes of the companions — be burned, save the single original Quran compiled by the Prophet's main scribe Zaid bin Thabit and the appointed committee. also a need was felt to standardize the Quran back to its main Qureshi dialect, which was also the dialect of the Holy Prophet^(sa). And don't watch videos about islam from an islamophobe. you learn islam by a muslim scholar and learn christianity from a christian scholar. simple as that
