@JosieAzar Picture this chain:

A --> B --> C

Failing B yields the inference that A, which is left of B, is also failed, because that's how sufficiency/necessity works. If A > B, then /B > /A.

Satisfying B yields the inference that C, which is right of B, is also satisfied, because that's also how sufficiency/necessity works.

Hi. My interest is piqued. Currently hovering around 160 and aiming for a 175 in June or August.

Whenever you're dealing with logic chains like these, it helps a ton to remember these rules of thumb:

Failing a condition negates everything to its left. (<---)

Satisfying a condition triggers everything to its right. (--->)

And: Can be split on the right side, but not on the left side.

Or: Can be split on the left side, but not on the right side.

Nice job! And incredible work on your blind review. Keep pushing!

@DeborahAdel Don't beat yourself up over it. Just keep practicing. You can and will get better.

Hi there. You've piqued my interest.
