Yes my comprehension test was at Wolverhampton University, you can't really revise for it because each group will have a different article to read. For example my group were given an article taken from Community Care about fostering and adoption, and we had to answer three questions relating to the article. Another group from my college who had test last week were given a completely article to read. But all the answers you need will be from the article. You should be fine, just keep referring to the piece of writing for your answers. Good Luck.
