I persuaded Faralda to let into the college and she told me to follow her, and I ran past and talked to the elf she was going to talk with. That didn't let me join but the quest marker was still above the elfs head. When I ran back to Faralda she was slowly making her way up the path lighting the candles but she stopped at the entrance. How can I fix this?
According to this site's bugs section, "As of Patch 1.3 the "Visit the College of Winterhold" quest may not complete if the persuasion or Dragonborn dialogue options are used." So just reload to a save before persuaded Faralda and cast the spell on the symbl of the college on the ground.
