[@iqrasangi.]

Starting my LSAT prep now. I'm freaking out about being so late, but also thankful to have found your channel. May we all succeed!d!

[@Yona0Yona]

I am starting my LSAT prep and was watching your old playlist, so happy to see that there is an updated version since I will be taking the version post-August-2023! Thank you for thinking of us youtube learners :D

[@KarlaFendi]

I graduated with my BS in chemistry and ive done a complete switch into going to law school. Just started my LSAT prep as well 🎉

[@jackxiang3844]

hahaha I'm chembio BS going into senior year and just started as well

[@lauren1675]

Starting my LSAT studying. Thank you so much for this series!

[@avsusky]

What an adorable and friendly teacher, thank you :)

[@danielmeyer51]

I really appreciate you sharing this knowledge to prepare us. Very thankful!

[@THEHOURISRIPE]

This was so good. I really love how you simplified the explanation of the complex language. Simple, but did wonders for me moving forward. This lesson as whole also increased my confidence for drill sets and practice tests. Even though theres still room for improvement. I feel like I know what I am doing which is half the battle. lol

[@elmenchoUSA]

Fr I even took the Kaplan course and literallt this explains stuff in a slower pace and way better😢

[@bomaebenezer2979]

I still have a year before taking the test, but I feel like I need all the time I can get. I'm glad that this was the first video I watched.

It's all about the Conclusion. 1. Find the Conclusion of the passage. 2. Understand what in the passage helps or hinders that Conclusion.

[@khaledbostani90901]

Thank you!

[@bbsmith915]

Great content!: 28:38 has error where the left column should have the header as conclusion signals. Maybe even a third column should be included where they overlap ;). Thank you for the videos!

[@sylwiacavalcant8800]

Great video. Thank you. I think there is a mistake in Practice Set #1. Only those who have registered can attend. The if-then statement should be: "If X is registered, then X can attend."

[@anirbanmukherjee5240]

Only X can Y means X is necessary for Y. However, it does not mean X is sufficient for Y. For instance, only those who are on Earth are in the US. That does not mean anyone on Earth is in the US. It means ~Earth --> ~US (those who are not on Earth are not in the US) and US --> Earth (those who are in the US are on Earth). The word "only" is very important. It can make a sufficient condition into a necessary condition. Only if is similar in that whereas if implies a sufficient condition (trigger), only if implies a necessary condition (the condition that must be true if the trigger is true).

[@flacan2020]

I disagree with albert and the libray, because you've excluded the possibility that albert can go to the library at other times. Obviously he goes when it does rain, but you did not say that's the only time he goes.

[@cdog1684]

when the the website be up and running?!?! i'm eager to practice!!

[@justineowusu]

very helpful video, thank you!

[@9aSu3]

Thank you for this training tool. When will you have the Insight LSAT website up? I am looking forward to integrating these videos and the website together.

[@sheritatillman779]

Thank you .

[@nicolasbuhtoiarov9268]

The “only” statements u keep Changing the order of the if then statements. Makes it super confusing

[@amariglover1445]

Thank you so much!!!

[@officiallypaula510]

Thanks for sharing

[@parsabahmanyar3892]

Thanks a lot for this series. In your old series you assigned problem sets from the "next 10 official, actual LSAT preptests" book. Wonder if those are still relevant / will you assign from that book again, or due to the exam content and structure change they are no longer an accurate representation of the exam?

[@WaltherPPK007]

No that book is no longer relevant because it contains the logic games section and it is outdated from 2011, hope this helps.

[@familyman650]

Thank you for the lesson! But would you please tell me what book I have to buy for homework?

[@Aqualchemy]

Godsend. 🙏🏽🙏🏽🙏🏽🙏🏽🙏🏽🙏🏽

[@christellapayne2520]

I am trying to understand the use of "only" and "only if" in logical statements. Specifically, I am confused about why the contrapositive of the original statement is treated as the equivalent original statement and vice versa. In logical terms, "only" introduces a necessary condition. This means that the part following "only" is required for the statement to be true. For example, take the statement: "Only those who have registered can attend." The word "only" introduces a necessary condition. Therefore, it should be written as A→R (If someone can attend, then they must have registered) and the contrapositive would be ¬R→¬A (If someone has not registered, then they cannot attend). Additionally, I want to confirm that the rules are the same for "only if." "Only if" also introduces a necessary condition, similar to "only". For instance, in the statement: "We can go on vacation only if we save money." The phrase "only if" introduces a necessary condition. Thus, it should be symbolized as V→S (If we can go on vacation, then we must have saved money) and the contrapositive would be ¬S→¬V (If we have not saved money, then we cannot go on vacation). I was taught that the part after "only" or "only if" is always the necessary condition and not the trigger or sufficient condition. The contrapositive will then follow logically by negating and reversing the original statement. Where are the discrepancies coming from?

[@reliancedevelopment9810]

You are assuming that if they didn't attend then they didn't register. or They could have not registered and still attended. If and only if they register they can attend fits your contrapositive ¬R→¬A

[@elizabethnnakwue1558]

Hi Christell, can we be study buddies?

[@Alatchakra]

What software you used to create such videos. can you please share.

[@TannaCoolstuff]

Where is the homework from? In what book or resource can I find the homework questions?!

[@jakevillaret]

How do we know you ONLY go to the library when it rains? Or am I overthinking it?

[@Chaos.Co-ordinator]

I think yes, you’re overthinking it. I’m pretty sure that conditionals have to be excepted as true on the LSAT. The LSAT requires NO outside info.

[@flacan2020]

@@Chaos.Co-ordinator I thought same thing and posted before I saw this

[@mariakelly323]

Does the wording in the if then have to be written exactly as shown? What if it's written a bit different but the symbolic is correct?

[@ProGymReels]

Hi, I put my email in and have yet to receive any mail as of two days now.

[@abandonallhope.1040]

I remember people telling me over and over logic games is easy to get minus 0 and i never got minus 0 even drilling all day so good riddance lg gone

[@fayzstern]

Ok… so I’m going to fail miserably 🤣😥

[@crispfriars]

Did bro just say no logic games???

[@maryanngambrah1963]

Yeah they removed them from the LSAT so moving forward it's just logical reasoning and reading comprehension and then the writing piece that you get either before you take the LSAT or after.
