This lesson will teach how to say "if" and "when" in your sentences. To do that, we'll learn two new grammar forms - (으)면 and (을/ㄹ) 때.
We're up to lesson 73, out of a total of 100. The higher up we go, the faster things might feel like they're moving. Remember to take your time to practice, and slow down if you feel things are moving too fast. Everything goes in order, so you can always re-watch lessons and take notes again until you feel comfortable with the topic.
