I went to Tanzania this feburary for 2 weeks for a medical placement and I had the best time of my life! It was so great to experience their culture as it is so different to ours. Also I learnt a lot in the hospital when meeting patients and learning about their cases. I saw things there that you would never see here in the UK. Also I watched 7 different operations which was one of the best parts of the experience, I can't imagine being allowed to do that here.
I did the work experience through Gap Medics who organised the whole trip very well. It was scary arriving in Africa at first but then a staff member met me at the airport which was really helpful.
I am happy to answer any questions you might have. But I would say go for it because you will have a great time!
