Hello. Just joined.
Hi there. I don't really know how to do this, so if it goes slightly wrong please don't laugh, (or you can if you want, I won't see it, will I?) I was wondering if anyone can tell me how weighting works. You need it to work out indices.It's used in Unit 15, itermediate, but is nowhere explained properly. If anyone can help I'd be very grateful. Thanks. :confused1:
