Answer
Why?
"Busy" is directly followed by the verb ending in -ing (working). "In" is unnecessary here.Incorrect:
B. I am in busy working on my project This sentence is wrong because "in" doesn't fit with "busy" when talking about actions.Correct Examples:
I am busy reading a book. She is busy preparing for the exam. We are busy fixing the car.Spaced repetition

Your points
Each card needs 14 points to finish. Each I Know adds 1 point.
How practice works
The rules (read this first)
- Each card is tracked separately. Every card has its own score from 0 to 21. The ring under the question shows progress for this card only.
- Each I Know = +1 point on that card. Tap I Know when you remembered the answer. The ring fills a little more.
- 14 points = Mastered. Tap I Know 14 times on the same card (not 14 different cards) and that card is mastered.
- 21 points = Expert. Keep going on the same card until 21 I Know taps — that is the highest level.
- This Week & This Month count mastered cards — not every tap. Your goal bar moves +1 only when a card reaches 14 points (mastered) or you tap Already know. Example: 10 I Know taps on 10 different cards adds to your total Points, but This Week stays the same until you master at least one card.
- Why isn't my bar moving? You are earning points on the ring, but the weekly/monthly bar waits until you finish a card (14 points or Already know).
Your goal: 0 / week and 0 / month means master that many cards — not that many random taps.
Quick example
You tap I Know on the card:
- Points +1 — your total points go up (last card in the top row).
- Ring fills — that card earns 1 point toward 14.
- After 14 I Know taps on the same card, it is mastered — This Week / This Month +1.
- After 21 I Know taps on the same card, it becomes Expert.
- Already know — skip straight to Expert; counts as +1 for This Week / This Month.
Points — total earned across all cards. +1 on each I Know.
The ring — how well you know this card (0 to 21).
Week & Month — cards mastered toward your goal. 100% = target reached.
