Questions about Theory of Knowledge
Do I need a tutor?
No. Everything here is made for studying Theory of Knowledge on your own, and your first 7 days are free. Already have a tutor on StudyBridge? Join with their code instead.
Will it write my essay?
No. Students never use AI on StudyBridge, and nothing here writes for you. Lessons, hints and worked answers are written ahead of time and checked, so the ideas and the writing stay yours.
Can my parents see how I’m doing?
Yes, if you’d like. Make a parent code in Settings and they get a free parent account with your plan, your study time and your practice. A parent can pay for your plan, too.
