Thanks for your feedback and your reply to my question.
Today, I considered your recommendation, so tried to skim over lessons and levels. I listened to four lessons including lesson 8 of level 2, lesson 30 of level 2, lesson 15 of level 3 and lesson 30 of level 3. As I had predicted, the word of above lessons were easy to me and I could understand over 95 percent of them. Also, I would ask you how I can use remind of levels, because after lesson 30 of level 3, the lessons are not active for me. Please let me know how I can use them.
Best,
Saeed
