What it asked first

A few questions shape the course around the learner.

  1. Where are you starting from with e-commerce?

    I've never sold anything online. I'm a complete beginner and I'd love a clear step-by-step plan.

  2. Which kind of online selling interests you most?

    I think I'd like to start with selling my own handmade or created products, since it sounds simpler to understand. I'm not sure yet, though, so I'd appreciate some help comparing it with the others.

  3. Got it, we'll start with handmade products and compare them with other options (like reselling or print-on-demand) along the way. What's your main reason for learning this?

    Side income alongside my job. I work full-time, so I can give it about 6-8 hours a week and I want to make my first sale within 3 months.

“I want to learn microbiology”

Microbiology from Zero: Gut Bacteria, Infections and Food

What it asked first

A few questions shape the course around the learner.

  1. Where are you starting from with microbiology?

    I took biology in high school, but that was years ago and I only remember the basics, so I'd say I'm a complete beginner in microbiology. I'd love to start with the bacteria in my gut and how they connect to infections and food.

  2. What's drawing you to microbiology?

    A hobby, I just find it fascinating. I'm really curious about how tiny organisms affect our own health, like why some bacteria are useful in the gut while others make us sick.

  3. How much time could you spend on this each week? And is there any date you'd like to reach a certain point by, or are you going at your own pace?

    I can realistically spend about 5 hours a week on this, and I have no deadline, so I'll go at my own pace.
