Hi everyone, hope your studies are going well. I just wanted to share an explanation of SUFFICIENT and NECESSARY conditions. This explanation is something I randomly came up with and I hope it works for someone trying to understand how that works in LAWGIC.

Explanation of the Sufficient/Necessary condition:

I want you to imagine that you are trying to enter into the most secure building on earth. There is only one way into the building, and that’s through a giant electronic glass door.

Conditions:

YOU are on the outside.

YOU have a proximity card that can be scanned to open the door

There is also a buzzer outside the door that you can ring.

When you do ring the buzzer, the door can be opened on the inside by a SECURITY guard.

Some days your proximity card works and some days it does not. Depending on if you are needed in the building on that day.

So there we have it.

Now:

SUFFICIENT: You scan your proximity card OR you ring the buzzer.

NECESSARY: The door opens

Scenario one:

a. The necessary thing you needed to enter the building: DOOR OPENING, has failed.

b. If that door failed to open what else do we know? Well, your card didn’t work or the guard was just not going to let you in that morning. IN short, door didn’t open. Thus all the things that could’ve made it open... someone walking ahead of you or leaving the building or using your card or the guard pressing the buzzer didn’t happen. )

I really hope this helps. It's lengthy but I imagine it would be much simpler as a short cartoon.

Hey all,

Like many, I've doing a number of PTs and find that parallel flaw questions are my weakest point in LR.

I was wondering if anyone had advice about when to use mapping on parallel flaw questions vs. when to intuit the flaw and answer choice match?

For example, I've just completed PT 53, and JY uses a conditional map for Question 21 Section 1. I realized after watching JY's explanation that trying to reason through or intuit this flaw would have been rather futile.

However, on the same PT—Question 13 Section 3, JY reasons through the flaw in his explanation. His explanation was great (it was a part relating to whole flaw) but I'm not confident in my ability to know when to use reason and when to use maps.

If anyone who is proficient at Parallel Flaw questions could share language cues or other details they use to know when maps are optimal and when they should reason through the question, I would really, really appreciate them!

Thanks so much, *also my first 7Sage post.

Hey! Does anybody know if you ordered a score preview for the October LSAT-Flex when it will become available? And where will we be able to see it? In LSAC or Proctor U?

Hi, I have two questions which might have one simple answer.

Can someone please explain to me why I shouldn't do a biconditional every time it says if m, not k (m --> /k). I mean the contrapositive would be if k, not m (k --> /m). So why not write it as m (---) /k ?

How does biconditional affect the rule of "if Sufficient condition not satisfied rule goes away and if necessary condition satisfied rule goes away"? when there is "m (---) /k" and the question says "not k" then the rule goes away?

Anyone got any tips/strategies for tackling PF? They're my worst area. I do pretty okay when it's a common invalid argument form but often times I can't really see what the flaw is if it doesn't follow that. Also not sure when to map out the stimulus and when I shouldn't.

Hey everyone, so I have been studying for about a little over a month and a half with 7Sage and I have just come to the decision to start again from scratch. The reason for this is I feel like the lessons, mainly the ones about breaking down words, sentences, phrases and being able to use this to identify what exactly the passages are saying (ex argument labeling, comparative statements, sufficient assumptions, etc.) aren’t clicking for me and I feel like once its time to take the practice quizzes at the end of the lesson I completely forget all that is taught and just read the passages without really using what I had just learned. Anyone have any tips on being able to apply these lessons as I go? Thanks in advance!

Hi all, hope you are all doing well. I am taking the November LSAT Flex and am currently, consistently, averaging -4 to -7 (-7 is my lowest score) on my LR Flex PT sections. I am hoping to be consistently at -1 to -3 per section and thought I check in here to see if anyone had some tips on how to best spend my next month studying. I generally get a few Nec. Assumption and Suf. Assumption Q's wrong as well as a parallel reasoning Q wrong. Would appreciate any advice/ tips. Thanks and best of luck with your studying and apps!

PT 11 S4 Q19

I am confused about the reasoning in this problem.

Hey if anyone has questions on logic games let me know! I’ve done them all.

Is anyone else having trouble getting in contact with LSAC? I have emailed twice and have been on hold for hours with no response.

Good Afternoon,

As I am starting my Reading Comprehension Curriculum, I would like to see if you guys have any tips or have any advice ASIDE from what JY explains at the beginning of the section. Feel like it could be super beneficial to hear from someone who has made it through this section and explain what worked best for them.

I am really confused about the relationship between these three things.

Sufficient-->Necessary, Cause --> Effect, Before-->After

Is it okay to understand like this?

All are in same logic?

I've been studying pretty diligently for the November LSAT but am still doing really terribly on the logic games section (like, really bad).

Do I have enough time between now and the November LSAT to nail down the games with the fullproofing system? And do you just recommend starting with all the "core curriculum" games?

Thank you!

Can someone please explain these to me. I don't understand them at all and I have reviewed the lesson over and over again. I always end up picking the SA as my answer. PLEAAASEEEE!!!!!!! #help

I didn't remember any of the inferences or how to diagram the games since I originally took them back when I was really bad, but i did remember taking them, and I'm wondering if i should even count the scores from this preptest as a result.

Hello,

Can someone please provide their process for RC blind review? Do you typically go through the answers using only your low resolution summaries or is it beneficial to reread the passage and do entirely new summaries then answer then go through the questions?

Hey guys! I was curious as to how you all have gone about studying different game types. Do I need to wait till I master one before moving on to the next? Or can I do a few at once? I'm taking the November test and logic games is what's holding me back. I'm only getting about 11-12 correct. Thanks in advance!

When you’re doing a necessary assumption question and an answer choice seems like it would be the answer to a must be true / most strongly supported question does that mean you should eliminate it?

Does anyone have experience with this?? On both LG and RC sections, I lost connection and ultimately, my vid cut out. They took 30 minutes and still couldn't solve it, which for RC meant that what I'd read was not in my brain anymore. I requested to reschedule rather than spend more time waiting for no reason.

Will I be able to reschedule?? I'm so upset!

So I'm currently going through the LG section. I'm curious to know what you guys do after each times LG section. In other words, do you repeatedly do the games until you're able to get the inferences. I'm unsure how to strategize that. Should I finish sections within the LG section and keep retesting the LG games and then move on? I plan to take LSAT in JAN so I'm hoping fixing my issue will help.

Does anyone have any tips for Must Be True or Necessary/Sufficient Assumption questions? I know they should probably be easy but they are the question types I consistently get wrong and find the hardest to understand

I had to call during my writing exam because the program had cut me out. They made me do a room scan again once I was back in the program. But, while I was on the call and my phone was on the table while I did so. When I hung up the phone, I put my phone farther away to the side and under the table. Is this going to be a problem? Has anyone had a similar situation occur?

This was gonna be my first LSAT and I wasn’t able to take it. I logged in and then proctor took over, then the computer began to lag like crazy. We kept on disconnecting. My internet is fine and is fast but when they took over, it went to crap. We tried to fix it for two hours and no luck. I went to buy a usb Ethernet adaptor to fix the connection issue by connecting my laptop directly to the modem. The proctor told me to call LSAC to see what we can do and he even said to download the chat box later to try again. I talked to tech support for proctor u and they didn’t know about this chat box (this one that allows the proctor to talk to you and take over your computer) but told me to email them to reschedule. Today was the last day to take the exam on the schedule. Wth! Am I screwed here? Anyone have/had this issue and is there a way to take the October exam still?

During the sign in process with my proctor, my webcam signal was not being received. I spent more than 4 hours with technical support resolving the issue, but when it finally was resolved, I was informed that my examination window had closed and that I needed to contact LSAC to request an extension. When I called the testing support line, a guy told me that all LSAT slots were full until January! That doesn't seem right... Does anyone know if there's a special route for people to sign up for a new session if they were unable to write due to tech issues?
