Business English Shadowing is the default subject for new accounts; Business Chinese Shadowing is also available.
The academic track includes Cambridge English (Starters, Movers, Flyers, KET, PET), German (A1–B1), and Chinese HSK.
Progress is saved per subject — switch subjects from the picker at the top; it never erases the previous subject's progress.
Explanations are in Vietnamese, while prompts and practice stay in the language you're learning so you get used to the real format.
Business communication subjects use the Shadowing method: each mission runs through 5 stages — Listen → Shadow → Overlap → Role-play → Done — to build speaking reflexes.
The academic track (Cambridge, German, HSK): each lesson has 5 steps (Learn → Practice → Check → Apply → Review), about 10–12 questions depending on the skill.
Writing/Speaking Check steps currently only need you to review the prompt and tap Complete — AI grading is temporarily paused for an upgrade.
To unlock the next lesson, finish at least 75% of exercises with average accuracy of 75% or higher.

Pro & VIP: unlimited new lessons per day, with more Practice sessions (see the table below).
Lessons/missions already opened today can be retried without limit. Daily quotas reset at 00:00 VN.
All plans include placement tests and rankings. Mock tests and the standalone AI Writing/Speaking hub are temporarily hidden while we upgrade them.
Ranked by lifetime XP. Each metal league (Champion → Silver) holds Top 10; outside the top 70 is Bronze.
When you move into or out of the Top 10 of a league, you’ll get a promotion/demotion notice.
Earn XP by completing lessons, daily missions, and keeping your streak going.
Your streak is the number of consecutive days you learn — study every day to keep the flame alive.
Invite friends to keep a group streak: when you both learn on the same day the shared streak grows, keeping you motivated.
You can send in-app reminders to friends when they're about to lose a streak.
Share your referral code/link from the Referrals page to invite friends to Camba.
When an invited friend joins and learns, both of you earn rewards under the current program.
The Camba rabbit sometimes appears on screen — tap to catch it and see your catch stats.
You can turn this off in Account settings. Catch count and rank appear on the Dashboard and win popup.
Placement tests help you pick the right level before starting the path — available on every plan.
Mock tests are temporarily hidden while we upgrade test quality; they'll return later.
