I cannot submit drills, even if I answered all questions. :(

#feedback- why tell us to avoid "only if"/NCs in answers and then place this one right after? lol time to backtrack

#feedback This lesson did not unlock/appear until I got to the parallel reasoning section. I struggled alot with SA because of missing this. I believe this is an error in the system

#feedback I think this lesson would have been easier to understand with a more in-depth beginning page and starting with a walk-through instead of 3 straight "you tries".

Does anyone have another resource or lesson to revisit to learn this properly? I have been consistently achieving around 90% correct on other sections. This one I'm barely above 50%.
