Not sure if this will help, but I would advise you to contact an engineer (either structural or civil) as they will have covered all the stuff in the exam and should be able to explain it quite well. You will probably find that you already know someone that's an engineer or you will find a friend of a friend that is!
I'm currently in 3rd year in Bolton Street and when my friend and I were in 1st year, we asked my friend's uncle to run through some stuff for the mechanics exam (some last minute cramming but it did the job!) - he is a civil engineer and has his own firm. He explained some of the stuff in a few different ways to try to find the best way for us to get it. He is really interested in engineering and to him, all the stuff we cover for architecture is basic, so it didn't take long for him to go through it.
If you find someone willing to help, give them a copy of your notes to read through first and then arrange a meeting with them. You might be surprised by how helpful some people can be. Another route that might help is if you get someone that is really interested in mathematics/applied mathematics and physics. We also enlisted the help of another DIT lecturer that is really sound and helped a good few of us with different problems from past papers even though it wasn't even his subject...
Failing that, you're welcome to join our cramming sessions as they usually work quite well - a few of us get together and cram like you've never crammed before! We will be going through the past papers and will call on whoever we can think of, in order to get them done!
Anyway, I hope you find someone!
