Whilst studying for the OCJA exam I often wondered what exactly I was getting myself into and was all the work worth it? Well the answer depends on what you are hoping to get out of it. Sure its a ‘nice to have’ on your CV. But that alone was not really a big driver for me. Having 6 odd years experience in java I didn’t really need it on my CV so for me, it was all about going back to basics and testing myself to see just how well I knew my trade.
The answer to that was not as well as I thought I did!
Having a plethora of tools and IDE’s that provide constant feedback and auto completion I realised that I was leaning quite heavily on these to do most of the ‘work’ for me. Only when I sat down and started to study for the exam did I realise that I was rusty. For me refreshing my memory was the biggest gain. I feel that I now have a better understanding of the language than I ever did.
You will really improve your java programming skills and foundational knowledge.
For me it was one solid week of studying and taking practice tests. I would say it would be closer to 4-6 weeks for someone relatively new. I would suggest taking some diagnostic tests if you are experienced. That way you will better understand your weaknesses and you can plan to target these areas during your studying.
When to book your test?
I would recommend booking your test once you can consistently pass practice exams and feel confident that you have covered all sections thoroughly. Test centres are booked through PearsonVue and generally speaking there are tests available in a short timeframe.
