I have been cubing for 3 months. I tried my hand at 3bld 2 months ago but haven't got a single success. I forget my whole memo after a few edges. I am still not able to understand speffz until now. Please help
when you learn speffz, just write down your letter pairs, until you're able to memorise them. Once you've done this for a while, start trying to memorise them without writing them down
