Where can I go to get help with certain types of questions to strengthen this area?
Also I have an app on my iphone to practice thought it's handy the answers portion to the correct answer is not very clear, is there anywhere where I can post the problems and maybe get someone to explain in better detail.
Thanks mush appreciated.
