Identified and avoided mistakes

I am prone to making silly mistakes. So when i decided to give the 202-450 LPI certification exam, i got jitters of my life how will i be able to clear the exam with mistakes looming over my head. But i got to practice on the Linux Engineer LPIC-2 premium practice questions online on edusum.com. I practiced and made silly mistakes here, learnt from them and prepared myself for the upcoming challenge in the best manner possible.
