The practice bank, open for self-study
Every set a teacher can assign, a student can also open alone: timed rooms that match the real exam, instant scoring, an explanation for every question, and mock tests calibrated against real score distributions.
Language exams
Academic and admissions exams
Academic sets total 10,400+ questions in 1,136 sets; language banks hold 5,500+ items. Numbers are read from the bank at build time.
How practice works
Open a set
Same timing, same navigation, same tools as the real exam: eliminate options, highlight, calculator and formula sheet where the exam allows them.
Submit, see the score
Objective sections score instantly. Writing and speaking return AI feedback within a minute.
Read the explanation, then retry
Every question has a written explanation that says why the right answer is right and why the tempting one is wrong. Unlimited retries.
Study partner match
Students who practice with someone finish more sets. Learn pairs students by exam, target score, and schedule, gives the pair a shared set each week, and keeps a small group chat. Block and report are built in.
Pairs and groups
Two people or a group of up to eight, same exam, similar level.
Shared sets
The pair gets a suggested set that neither has done, alternating skills.
Weekly board
A leaderboard by exam, reset every week, so a new student can win this week.
