First, the maybe... A coworker and myself traveled 6 hours to Philadelphia Wednesday for a Thursday AM RHCSA exam at a kiosk location... 30mins outside Philly, we receive a cancellation e-mail due to weather.

Luckily, we were able to get an immediate reschedule for the same timeslots another two hours away in New Jersey. We jumped on it. We got up very early in the morning and drove through the snowstorm that cancelled the original exam, making it to the NJ location with just 20 minutes to spare. We had called to confirm multiple times that this location's test was still on... Guess what? Nobody even showed up to the office!
So, here's try number three and a day later. We're headed back in Philly for one last attempt to take the exam...
My co-worker and I are both senior UNIX engineers for a large company, but are just recently switching over from AIX to Red Hat. My co-worker has been studying a good amount for the past few weeks, and I've been casually browsing the objectives. We both took the in-classroom RHCSA Rapid Track Training and have accounts for the learning subscription, so we've been able to practice a bit with labs.
Hopefully that'll be enough. The nerves are starting to set in, but I'll give it my all. If I'm successful today, I plan to immediately start prepping for the RHCE. Wish me luck!
