If you want to find out more about Dianetics and Scientology, the best way to do this is to read an L. Ron Hubbard book on the subject. I personally recommend you read Learning how to Learn.
This book really helped me with my education. Before reading this book I wasn't doing well in school at all but then I learned why I was doing so poorly and how I could remedy this problem. If not for this book I believe I would still be doing bad in school.
