The remaining 10% is where most courses bury you in Greek letters. The Express Lane refuses to do that. Instead, it teaches the smallest set of concepts that lets you place a real (paper) trade in under an hour: how to read a chain, what a delta of 0.30 actually means, why theta hurts you, and what IV rank is telling you about the price you're paying.
If you finish this module and the next four, you can place a long call or long put with a clear thesis, position size correctly, and exit at a planned profit or loss target. That is the entire purpose of Express Lane — to get you trading paper money intelligently in the shortest possible time. Depth comes later, in the full curriculum.
