Any piece of information is appreciated.

I am actually a mix of junior and senior developer right now because I have less experience than my team-mate, but I have been with the company the longest out of anyone on the team, my manager excluded. Between us five though, we support sites for about 700 employees and the public, as well as various field sales reps around the United States. Need for OCP certification. uCertify is giving 70% discount on OCP test simulation. Want to know more about the ucertify product, newcomer in certification arena. Is it worth to buy this? I'd also be interested in any opinions regarding necessary formal training, education, certifications, etc. Any piece of information is appreciated.
