your going to hear this from me and pretty much everyone else who struggles with this section "Just keep at it, eventually it will click"
I think what helped me ease it off my mind was that I didn't care for that section a whole lot, I was doing really good at 4 out of the 6 sections of the PAT and I was confident that those 4 "good" section were gonna carry me to at least a 19 or 20.... I was right, I SUCKED with angles, and some pattern folding
My advice is focus on the sections you are best at and leave the hard one at the end. Do it a last, if you can figure it out, just pick an answer. Never leave it blank. For example, when I did practice last year, I was very bad in pattern folding also and time is running out, I click C for all the answers and I got around 7 right out of 15. Still better than nothing right?
