I like the methodology of the course, the flexibility of schedule and over all, the free option Because, my economy is not the best now, but , Iam pretty sure that I will get The Certification for C1 .This course help me a lot to improve my English. I really recommended to take Upper-Intermediate English, of course it takes time and effort ,and you will get there.
I went to fast with the course. Iam thinking in go over some task , now that I got the time to do it right. This is other advantages, you can go over and over as many time as you need. This work for me, because sometimes Iam in a hurry and I May come back and redid.
thanks, very much, blessing.
