Nice job on getting through that last one (I know, I probably already told you that). Seriously, sim 3 went like hell for me too. I'm not sure what it was, but I got the worst review I've gotten so far on that one. Sucks, but walk it off and keep studying. The technique of throwing a ball around to help solidify your callouts really helps as well, that is, if your roommate is down with it. :P
By the way, sims 4-7 really solidified my technique I feel. My sim partner also showed a huge improvement between 4 and 7 as well. I think it takes most people 3-4 sims to really settle in, so I doubt you're unique in that respect.
See ya around. You'll be on the line before you know it I'm sure.
Now if I can only figure out how to land this thing in a crosswind...hmmm...
