Doing a placement in Ghana, for however long, is certainly an eye-opening experience. If you go with an open mind, the culture difference will be fascinating but not daunting.
Ghanaian people are known for being friendly and this is certainly true. They are all keen to help you out and as long as you are friendly but firm (when they all want to encourage you to get on their tro-tro) then things will be fine.
A few words of advice:
1. If you are based in a major city, be prepared to hear lots of car horns. Drivers love to use their horns, it seems to be a sign of their dominance on the road! And taxi drivers seem to think it is a sure fire way of gaining a passenger even if that person has no interest of hailing a taxi!
2. Ghana Time! If someone offers to meet at 2pm, it will mean 3pm! Everyone is so laid back that the idea of starting on time or even early is unheard of!
3. Linked into number 2 is a word of warning when going to a restaurant in Ghana. Do not arrive at a restaurant dying of hunger in the hope of eating quickly. Service is notoriously slow and even so called fast food restaurants can be slow to produce the food. Think of it as another aspect of the Ghana laid back culture!
4. Be careful of gutters! They are mostly not covered so be careful of your footing (I speak from experience!)
5. Although not overly spicy, the food can sometimes take some adjusting for some volunteers. Stomach upsets in the first few weeks are common, don't worry!
6. People often advice to wear long sleeved tops and trousers in the evenings to avoid mosquitos. If you are in more remote areas this is certainly true. But if you are in major cities, you can wear short sleeved tops. As long as you are wearing insect repellent!!!
In terms of Projects Abroad, I can not praise them enough. Some people say it is quite expensive, but they are friendly, help you pre-departure and constantly whilst you are there. From meeting you at the airport, to the inductions (including helping you get a Ghana SIM card and changing money), to the weekly quiz nights, to the regular feed backs with the placements and accommodation, it is reassuring to know that they are there if you need them. But they also give you the space to be independent and have a great time.
I would go back there tomorrow if I could! (I even miss the drinking water sachets, heaven forbid!)
