Problems on Computer vs Pen/Paper

[robustening]

Qbank avg. = 74% and i’ve done 2k questions. thought it was weird considering my EOCs were consistently 80%+. i just did a few qbanks pen and paper and the scores were more commensurate with my EOC scores.
anyone else find they do better w/ pen and paper?
and what are the thoughts on the qbank for dec 14? this is my first time taking it but i think the Q is harder than EOC
