Hi,
Just be confident! here are some tips...
for the summary, make sure you include all of the points that the question asks you [usually 6 points] and always rephrase it [write in your own words] . for the article/essay w/e just make a quick 3 minute plan of what you intend to write.
There's usually an application that you have to fill, read the instruction carefully because they're not the same on every part.
Best of luck
