 I've also been scratching my head over how [Tom Dubick](http://archive.fabacademy.org/2016/charlottelatin/students/999/about.html) takes  a cohort of high school students through the Fab Academy every year. We need at least one Tom in every country. I noticed in his students' documentation that they go through a short Pre Fab course before starting the Fab Academy. So I thought it couldn't hurt to try it here, too.

 <p>I've set up <a href="https://www.fabisa.is/N%C3%A1msefni/Pre-Fab/0-yfirlit/">Iceland's first Pre Fab course</a>. I think it's essential that prospective Fab Academy students try a few things before starting the course itself, so that they know what they're getting into! Before I started the Fab Academy, <a href="https://fabacademy.org/archives/2015/eu/students/gunnarsson.thorarinn_b.b/about.html">Þórarinn</a> taught me to mill on the ShopBot, <a href="http://archive.fabacademy.org/fabacademy2016/fablabreykjavik/students/272/index.html">Hafliði</a> walked me through making a simple capacitive sensor and <a href="https://fabacademy.org/2022/labs/isafjordur/students/arni-bjornsson/about/">Árni</a> helped me set up a website. It was unplanned and informal, but it helped me a lot. </p>
