I wasn’t able to fully complete them but it was really great

Sentence 2 was more challenging than the previous ones. But it's great to finally be able to say simple sentences in different tenses. It's a better way to express what you've experienced.

I now know how to makes sentences in past, present and future. Also, learned alot of words to make these sentences

This is a great curriculum! I loved learning about past, present and future tense. They are really important to know and it feels great saying I know these tenses in the Korean language!
