Instead of students having to adapt to certain tools -- text books, or lesson plans -- that might not be a natural fit for them, Geekie claims to help students find their own way, and follow a different sequence. When a student loads up the app, it asks them to complete an assessment that shows where they would rank in the National Admissions Exam, and where the gaps in their learning lie.The next challenge for Geekie is how to apply these lessons to the whole of Brazil and expand internationally.
