Knowing your conjuncts from your disjuncts

Knowing your conjuncts from your disjuncts!
So I have finally paid for the Grammar at Work course! It’s hell (which means it's actually a very good course). I did the starter test and I got 53%  - not bad but I have to admit a lot of that was guess work. I have vowed to myself that I am going to give my all to this course. I’ll know by Conjuncts from my disjuncts by the end of it. And with any luck I’ll also know where to place comma’s which seems to be the worst of my flaws. I won’t lie...
