Your videos got me from zero understanding of how to conceptualize logic games to getting -2 or fewer on full sections in just a week. Thank you for your very clear explanations!
Glad to hear it! The playlist it’s in has a couple dozen other examples, including major games types like grouping, in-out games, and mapping games. If there’s ever one you’d like to request in particular, let me know!
Sure! That last clue says that Y is before V *if and only if* P is first. This is called a bidirectional conditional clue, and it means that both conditions have to be satisfied or neither of them can be. In other words, if you know P *is* first, then you also know Y has to be before V. AND it works the other way as well, if you know that Y is before V, then you know P has to be first. But this also means that if you know P *isn't* first, then Y can't be before V. In this particular game, since the elements have to be at separate times, that's the same as saying V has to be before Y. On #11, P isn't first, and so Y can't be before V, which means that V has to be before Y instead. Does that help?
@@keiraharris3594 yes. if you see "if and only if" the conditional clue works both directions. so, imagine an easier clue like "A is in if and only if B is in." That tells you BOTH that if A is in, then B is in also AND that if B is in, A is in also. On top of that, you'd also know that is A is not in, B can't be in either ('cause if B were in, A would have to be in, but it's not, so B can't B), and vice versa. Normally, conditional clues only work one direction, i.e., if you're born in Dallas, then you're born in Texas definitely does NOT mean the same thing as if you're born in Texas, then you must have been born in Dallas. But bi-directional conditional clues (if and only if, if but only if, etc.) do actually work in both directions.

Honestly your the first person to actually make sense of logic games, your explanations are simply amazing…. Thank you sooo much!
you're so kind! i'm glad it's helpful. hope to upload some more soon :)

That's amazing! Thank you so much for letting me know. Good luck on your test!
Thank you foor this.
This is one of the most helpful videos on logic games I have found on youtube.. Thank you sir!

This is tough.
the speed or the strategy?
I’m not picking it up, but I will keep studying. The graph is good but I’m getting frustrated quickly still. Just need to practice more.
Can you explain for #11 why does v have to go in front of y if that is not stated in the rules?

@@polymathematic Okay so when "if and only if" is used in the rule if p is not first then the rule is switched?

AH! I love ordering games but your way was the best explanation.
Thank you!
