It worked for me to "mask the symptoms", i.e. heart racing, and chest pain that anxiety induced... without causing too much drowsiness. It still made me feel tired tho bc it dropped my blood pressure, and I was on the lowest dose. But I didn't really feel "calm". I still felt physical symptoms of anxiety (tense shoulders, muscle pain etc). Also if you are in a testing environment beta blockers affect memory and recall. So I had to stop taking them.

Be confident. Too many days are wasted comparing ourselves to others and wishing to be something we aren't. Everybody has their own strengths and weaknesses, and it is only when we accept everything you are- and aren't- that you will truly succeed.
