Sorry but it has to be Met, just because of the sheer volume of material there is to learn. This might be less of a problem with modular, as you can spend as much or as little time as you need depending on your existing knowledge. On the integrated course however you have a set amount of time and doing general nav, ops procedures, instrumentation and met in two months is a tough prospect!
Have to agree about the ops and air law, tho I did ok. Thank the lord for Bristol GS website, it's got me through at least 4 of the "knowledge based" exams!
