Is dental assisting school/working as a dental assistant difficult?

I am going to be starting a dental assisting program next week. It is a 12 month program at a trade school. I'm just wondering if the program is difficult. Some people say it is while others say it isn't. I know a lot of people get hired during their internship but some don't. So I did some calling around and I found a hygienist who volunteers at a clinic. She said I could come to the clinic and volunteer after completing the Dental Assisting program. If I need experience to put on my resume... Is dental assisting school/working as a dental assistant difficult?
