Yes, those pencils are fine. basically scantrons will read any pencil as long as its dark enough. Even when you mark your answers super light, barely shading, you’d be surprised it still reads (i know ppl that mark their answers very lightly). No 2 pencils are just any wooden pencils with HB 2 or B2 marking on them indicating the graphite type. When i took the SATs i used lead pencils (mechanical pencils) only because i like the finer tip, and just had random pencils i found lying around the house for backup. Dont worry so much about such miniscule details, as long as you’re prepared youll do fine. But dont forget a good eraser!
