- How might posture affect general well being, including arthritis and back pain.
From our Students ...
" ...it is very informative and worthwhile. I am glad I started the course. Of the many available from different schools, this offers the best value for money. "
- Sonia, studying Human Biology
"The information given was excellent, but the assignments also made you look further to find answers yourself and I find this a much better way of learning than just being handed all the answers. It has given me a grounding knowledge in human biology which is perfect as I am applying to study Chiropractics at university next year. I couldn’t have asked for more from my tutor. She was very thorough and extremely helpful with any problems I encountered".
