well i have no problem talking to people, but i just get really nervous when i give out presentations in front of a crowd. I keep on shallow and shallow, which makes myself look dumb and shy, and i get more nervous. I usually get really bad grade on my presentations or i usually just " ditch" the class on that day and take the F...... I mumble a lot when i talk, people don't usually understand me the first time.
This is the whole point of a public speaking class. Let me break down the class I took for you.
The first "presentation" we gave was our third class meeting. We simply had to talk about ourselves for 1 minute. Some people went up and were overly excited, most others were pretty shy and just talked about their major and what they do for fun.
The next meeting, the teacher handed each of us a piece of paper that had the good and bad qualities of our speech (did you project your voice, make eye-contact, read off a piece of paper, sound rehearsed, fiddle with your feet/hands/hair, mumble, talk about something interesting, show confidence, etc.) along with our grade (everyone automatically got an A just for going up and talking).
Next the teacher paired us up according to people's abilities (ie- someone with a strong quality was paired up with someone who was weak in the same ability and vice versa). We then went out on our own and practiced the things we were weak on according to her instructions (practice saying these tongue twister out loud to your partner, hold your feet/hands still as you talk to your partner, etc.). After a couple sessions of this we did another speech (informational... ie- teach the class about something for 3 minutes).
The routine continued, but switching partners after each presentation. Overall you give 3 real speeches plus 2 informal "talk about yourself" speeches. It's an easy "A" as long as you show up. The teachers realize most everyone there is afraid (or at least anxious) of giving speeches in front of classes, which is why the classes are generally no more than 10-20 people. You get to choose your own topics, everyone is encouraging and no matter how bad you screw up, noone will laugh since they're too afraid the same thing will happen to them. It's a huge help and will be one of the most useful non-academic skills you will use. Trust us on this. It's not worth throwing away grades, school options, and (eventually) job opportunities, all because you couldn't talk in front of 10-20 people for a few minutes. If you can talk in front of 1 or 2 friends, you can do this!
