You have really missed the point in what a lot of folk are saying. Passing an A+ is not the golden ticket to landing a job. In fact I weed out certification folk early on as most of the answers are available online in brain dumps. Utterly pointless (unless they mean I hit my vendor discount quotas ).
Put on your big boy pants and search for local firms in Croydon offering IT Support. Then, go and have a discussion. You have more than enough chat in the brief post you made to get a discussion at least.Finding a job to use any of this experience or knowledge is foreign to me.
Sure, aptitude and willingness is great, but how do you apply for a job if the requirements clearly state a need for an A+ qualification at the very least?
