Why LockIn exists

Before college I went to flight school. There, you learn every word on the checklist before you ever touch the controls.

In college it was the opposite. Practice problems came before anyone explained the words in them, and the biggest problem on a test was often something no drill had made me do start to finish.

So I built the study tool I needed: paste your notes, and LockIn starts with the key words in plain English, walks you through one solved example before every problem, and ends with you building the whole big thing yourself. One thing on the screen at a time, because that's how my brain works.
