A course slot is one of the courses you are studying right now. Your plan says how many you can hold at a time.
| Plan | Courses at a time |
|---|---|
| Fresher | 2 |
| Scholar | 9 |
| Distinction | 18 |
| First Class | No limit |
Nine is a full semester load. Eighteen is a full year.
Slots are not credits
Two different things, and they run out for different reasons.
A slot is how many courses you can have open. A credit is what you spend when the AI makes something. Reading a course in a slot costs no credits at all.
Filling every slot does not cost you anything. Nine courses open and never asking a question spends nothing.
Taking one off your list
Open the course, tap the ··· at the top, and choose Remove from my courses. Everything you did in it stays — your marks, your summaries, your tests — and comes back if you add it again.
It still counts as one of your courses for 30 days. Worth knowing before you remove something to make room for a course you need this week: the room will not be there in time.
