I would like to ask for a little advice about choosing right course to get me to the place I want to get.
I have graduated in September 2012, achieving Masters degree in Religious Studies from Jagiellonian University in Poland. I had a couple of courses in Psychology and Psychology of Religion and would like to continue my education in field of Psychology. I would like to know what kind of course could I start to be able to come back to and further develop myself in academic work. To complicate it further, as Psychology back in Poland is treated with much more emphasis on social studies than science, I haven't needed and indeed don't have any exam or degree showing numeracy/math/science knowledge or skills.
Would I need to pass any numeracy tests or A levels? Should I get second Masters degree to be able to get to research courses afterwards? Or should I aim for conversion courses?
Any advice would be appreciated

Where are you hoping to study? If it's the UK, I would recommend contacting the British Psychological Society, as postgrad research degrees here usually specify that you need to have done a degree which would make you eligible for BPS graduate membership. They should be able to advise you of the requirements to get on to a research degree.

Yes, I'm hoping to study in UK, preferably in London area. Thank you for your suggestion, that's something I didn't think about.
