    1 flagged finding: a quote attributed to a vague, uncitable collective ('Network+ and CCNA instructor consensus') presented as a verbatim quote.

    Before
    "Subnetting is a physical skill like touch typing. Reading about it does not build fluency. Only repetitive practice under time pressure, aiming for 30 seconds per problem, builds the speed that exam conditions require." - Network+ and CCNA instructor consensus
    After
    Subnetting is best treated as a physical skill like touch typing. Reading about it does not build fluency; only repetitive practice under time pressure, aiming for 30 seconds per problem, builds the speed that exam conditions require.

    Why: Removed a quote attributed to a vague, uncitable collective ('Network+ and CCNA instructor consensus') presented as a verbatim quote. De-attributed to plain unattributed prose preserving the underlying claim.
