Are you aiming to go to UBC? It's one of my top choices. I just broke 160 mark yesterday and have been making a slow progress since I started PTing(sigh).. hopefully I will reach 165+ soon!
Especially because you can get a 180 without being perfect lol. Being upset cause you don't go -0 is wasted energy--don't worry about it, hakuna matata.
How is a 180 Watch any better than the watch JY recommends with the little turny thing( technical term)? Do you not have to reset it after each section?
