Rehearse delivering the presentation aloud, practicing pacing, eye contact, and vocal emphasis on key analytical points.
Rehearsal is where a presentation actually becomes confident: practicing out loud, not just silently reading slide notes, builds the fluency to speak naturally, catches awkward phrasing before the real audience hears it, and reveals exactly where more or less time is needed.
Three specific delivery skills matter: pacing (slowing down on the most important analytical point so it lands, rather than rushing through everything at one speed), eye contact (looking up from notes or slides regularly instead of reading down at them the whole time), and vocal emphasis (stressing the key word in an important sentence, the way "true" gets stressed in "whether the stones are TRUE").
Mastery looks like: They rehearse their presentation aloud multiple times, applying deliberate pacing, regular eye contact, and vocal emphasis on key analytical points.
Common stumbles: Only reading through notes silently instead of practicing aloud; delivering every sentence at the same flat pace and volume with no emphasis on what matters most.
