I am looking to return to office work after almost 17 years away. Previously I worked in accounts - sales, purchase, nominal ledger etc and would be keen to go back to that. Does anyone have any suggestions as to what refresher courses I could go on to bring me back up to speed? I notice that SAGE and SAP seem to be popular in the workplace and I have looked into some Pitman courses but I don't want to waste time doing something that will not be relevant. I am quite computer literate and I have recently completed a degree (not related to accounts in any way). Your suggestions would be greatly appreciated.
