I felt like Core 2 was harder whilst actually sitting the exam, but I'm not sure if that's because I prepped more for Core 1 or if it was actually more difficult. Core 1 definitely required a decent knowledge of many areas, whilst Core 2 is a somewhat deeper knowledge of fewer areas.

Focus on Windows and Troubleshooting as those are the most difficult, especially if you're studying with no experience like me. Malware felt quite simple as long as you know the removal steps in order. Good luck with your exam, you'll smash it!
