300?? wow.
ummm yeah he's really good. He came to our school and spoke about stuff. Though we only had to pay a few dollars.
he's a really good speaker and he makes it fun, not like some boring lecture. It's all on techniques on how to study and how to succeed. If you seriously follow his tips and do what he says you will do better. But you have to stick to it.
Ultimately it's your choice whether or not you want to pay the money. He is inspirational and good to listen to.
i won't be a judge on whether or not it's a waste of money though... because we didn't have the full seminars, only the school ones.
However, if you suggest it to your school you might be able to organise for that, then everyone benefits.
