One of the best things about Spark was that it was not built in a vacuum.

It had oxygen from Day 1 - thanks to the two high-school online tutors and their 100+ students we've been building it with.

We had feedback at every crucial juncture.

For example, here's feedback from a couple of 8th graders:

I loved this for two reasons:

1. It surfaced a product gap: we need the "skip question" feature.

2. It's proof that these students are deeply engaged while taking the quiz.

The Pareto principle tells us that 80% of users typically rely on 20% of features.

Great product teams obsess over that 20%.

That's exactly what we've been doing with the quiz..which increasingly looks like one of Spark's core features.

Quiz: Features & improvements

We've just released a flurry of improvements. Here's a summary:

• Topic based quizzes: You already know Spark can generate quizzes from a specific video. Now, you can select a topic instead: Spark automatically pulls relevant content across multiple videos and generates a quiz from it.

• "Fire & forget" quiz generation: Generate quizzes in the background. No more waiting. You'll get an email when it's ready.

  

  New feature: Background quiz generation

• Parallel quiz generation: "Fire and forget" not one but multiple quizzes at once.

• Longer quizzes: Want 20, 30 or more questions? Spark can now do this without timing out.
