Passed part 1 yesterday with 90%.
Gone thru the study guide - each and every page almost two times. Discussed with a friend who also appeared at the same time. Attended an offline webinar training session.
Overall preparation around 2-3 weeks with around 2-3 hours every day, last one week almost 20 hours.
