In need of GH3 help

[Nemo17]

OK so I'm not exactly a Guitar Hero. I'm stuck on Hard mode on Raining Blood.
Although I really like this song it's annoying me greatly.
I keep failing on Mosh 1. I think it's Mosh 1. It's the section with a lot of Hammer ons near the beginning of the song. Could anyone please help me by giving me a tip on how to do this?
An E-Mail or a reply will be fine :)

go into practice mode, chose the section of song you need to work on and the lowest speed play throught it untill you cab do it then build up the speed untill you can do full speed
