I doubt it was a benzo for an exam situation. Those often make people kind of woozy - I think it’s much more likely that it was a beta blocker.
Thats why the BBs are “PEDs” for shooting events. They can basically block the physiological stress response, and certainly could be used in that one off type scenario (so could a benzo, but I would think of that for something more like dealing with a fear of flying or something - something where you don’t need to be 100% with it)
As @nerdyparent said, SSRIs (http://en.wikipedia.org/wiki/Selective_serotonin_reuptake_inhibitor) are the big ones and benzos (http://en.wikipedia.org/wiki/Benzodiazepine) for more episodic anxiety like panic disorder but you might also see people on SNRIs (http://en.wikipedia.org/wiki/Serotonin–norepinephrine_reuptake_inhibitor), tricyclics (http://en.wikipedia.org/wiki/Tricyclic_antidepressant), and MAOIs (http://en.wikipedia.org/wiki/Monoamine_oxidase_inhibitor) and more rarely, atypical antipsychotics (http://en.wikipedia.org/wiki/Atypical_antipsychotic)
