The first time you sign in, AlveoAI asks a few short questions: your stage of training, where you're studying, which exam you're preparing for and, if you know it, your exam date.
Your answers shape everything that follows: which questions you see, how the tutor explains things, and the countdown on your home page.
To change them later, open Settings → Personalization. AlveoAI picks the change up on your next message.
