I am a 13 year old student and have intetermediate computer skills. I would like to study for A+, I+ and MSCE certificates but I dont know where to start. I dont whether I should go to a computer tution or study by my self with books, can you recommend anything to me?
I live in Auckland and I also dont know where is a computer tution place either.
Can you recommend some study books too? and if I do study by my self where would I have to go to take these test?

Thank you very much
