Just thought I'd share. Bought CRTO in 2020, sat the exam in 2021 but had to abandon it for personal reasons, and came back to it five years later. The course was almost unrecognisable, with different C2 options, different lab platform, different exam format.

Wrote up the full retrospective on the blog, including the bits I found most interesting (the tradecraft full-circle back to raw LDAP queries, the 2025 exam redesign, what the gap actually feels like coming back).
