Learn with the #1.
Study with AI.
1TA is an online school for international STEM curricula. We teach IB, AP, IGCSE, and admissions tests to students preparing for top-50 universities — live, in small groups, from anywhere.
The name is the promise. Every instructor on the platform was a #1 in their own right: top of their cohort, then top of their subject. We don't hire generalists and we don't cover subjects we can't teach exceptionally.
#1 instructors, plus an AI that never sleeps
A great teacher can only watch one student at a time. So every 1TA class is paired with an AI teaching assistant — a TA — that sees every problem a student attempts — which ones they hesitated on, which ones they guessed, which ones they got right for the wrong reason. The teacher sets the direction; the AI catches what happens between lessons.
How it works
Diagnose
A short placement session maps what a student actually knows against their curriculum, topic by topic.
Learn live
Private or small-group lectures with an instructor, timetabled in your own timezone and recorded to your Library the same evening.
Practise with your TA
Between classes your AI TA assigns targeted problems and flags weak topics before they become exam-day surprises.
Sit the mocks
Full timed papers under exam conditions, marked against the real rubric so the final grade is never a surprise.
