EX200 certification exam requires practice on another level. So i started searching for practice resources and zeroed in on RHCSA mock tests that helped me understand the syllabus topics thoroughly and also got me practice on the questions that are most probably asked in the exams. What more! I did not pay a bomb for all. Just a miniscule payment once and i could access it for unlimited two months. Day after day my score improved and i was prepared for the final actual attempt.
