The first thing is to find information about the test. This way, you know what to expect. Then you can make a plan of what to do. Really, as far as I'm concerned, none of the texts you mention will sabotage your chances, so just pick one and use that. Of course, also look at other resources - a quick search online will give you lots of material. Don't forget capital letters and punctuation. They might look like tiny details, but they tell us exactly how much attention you are paying to your English skills Good luck~!
