Hello everyone!

I recently found out about certifications and the big impact they have on you getting a job, I feel a little silly admitting that though. I have been studying for about 1 month now to get A+ certified. But I am very concerned on how much time I should spend studying. I plan to take it before I graduate my senior year of high school. (This school year) I've spent $50 on a big book with loads of information that also contained some practice exams on a disc. I've been around computers most of my life, and I've been taking them apart since I was 13. I have experience doing repair and maintenance for friend's and family, and overclocking is a hobby I spend a lot of time on. (Would spend more time if I had the money to constantly buy new parts.) I seem to know about half of what I've read so far in my book, but everything I read about A+ seems to be mixed.
"Oh it's so easy!"
"Failed it twice!"
I just found out about this site today and have started watching the videos to further help my studies, But I am very worried about failing this test considering the cost of it, and the lack of income on my part.
Does anyone have any test taking tips for this either? What to expect? I don't know anyone personally that's even interested in technology like myself, let alone have taken the A+ exam.

Sorry about all the text, and thank you to anyone who reads and replies.

Extra concern: I am also getting told on another forum to just go to technical school and do certifications instead of paying 70k ~ 100k for a 4 year degree in computer science. (Prices of the local schools in my area) It defiantly would be cheaper to do what they suggested, but is it the best choice? I really would like to be good at my job and actually get hired.
