Mostly as the layer that keeps things from slipping. Read a Brick or work through a block, then put those cards into rotation so the material comes back weeks later instead of disappearing. Most students use it in short sessions rather than long ones, often as a warm-up before studying or in the gaps between other things.

No. All 14,000+ are already written and reviewed. You choose which subjects and how many cards go in a deck, but you're never writing the cards themselves. Making a deck takes a few minutes.

You rate every card Don't Know, OK, or Nailed It after you flip it. Nailed It pushes the card far out, Don't Know brings it straight back, OK lands in between. Set your timeline and Study Stream turns that into a daily card count and tracks what's due.

It isn't meant to be. Flash Facts is for retention, not first exposure. If you're learning a topic for the first time, you need something that explains it, and if you're testing exam readiness, you need questions. Flash Facts keeps what you've already learned from fading.

Flash Facts on its own gives you the cards and Study Stream. Rx360+ adds Qmax, Rx Bricks, and Express Videos, all linked together, so a card can take you to the Brick that explains it or the question that tests it.
