The site ielts.up is good?

Hi, I have to do the IELTS exam and I want to know if the site ielts.up is good to improve my preparation, because I tried to practice with a reading and it seemed too easy. Is my english improved or the reading was too easy for an IELTS exam? I will be very happy if someone answer!

This is the site: http://ielts-up.com/index.html

Thanks in advance
