Dear applicant when things seem to appear a bit messed up, the first thing you can do is to keep calm and recall the things that you remember rather than panicking about what you forgot. If you gain confidence after discovering that you finally recall something your urge to prepare the rest of the things will grow faster. Because of lack of confidence most often we face drawbacks, so discover your strength and weakness too, revise the strength and work on the weakness.

Good luck!!
