Have you tried using creating Practice Blocks using our Study Plan? I think you'll find them helpful in guiding your practice up until test day.

Click the time number in the top right (above the green bar). That should hide the timer. This works just like it works in LawHub.

It's not as analogous as one that presents "Y -> Z," but I'd be open to picking the answer you describe. It may very well be the most analogous if we don't get another answer that's exactly the same, but with "Y -> Z."

Hey! Unfortunately I don't take 1-on-1 students right now. I don't have any plans to teach any live class/courses the rest of this year, but don't worry -- I'm working on some new video lessons that should be up in the next few weeks. I might occasionally pop in to teach a live class every couple of weeks next year.

Are you thinking something like a hint system? You can press something to show you the Q-type during a drill?

Are you finishing the sections when timed? I strongly recommend trying a few sections where you don't care about finishing. Just focus on getting every question you attempt correct; if you end up having to guess on 5 questions, so be it. There's a good chance this approach results in a higher average LR score.

Learn about the Ad Hominem Fallacy from Philosopher and Environmentalist

Philosopher: You’re an idiot. Even if we care about nature, banning fossil fuels would lead to massive deforestation as manufacturers turn to biofuels as a substitute. So we shouldn’t listen to your smooth-brained policy proposal.

Environmentalist: Ad hominem! Ad hominem! And you call yourself a philosopher.

Philosopher: No. I didn’t commit the ad hominem fallacy.

Environmentalist: But you insulted me and said I was wrong.

Philosopher: No, no, my illogical friend. There’s nuance to this. We commit the ad hominem fallacy when we attack the source of a claim as support for why that claim is wrong.

For example -

You smell like a cesspit. So, we shouldn’t listen to you when you tell us to use eco-friendly soap.

Here, I’m citing to your stench as a reason to reject your recommendation. But the idea that we should use eco-friendly soap should be evaluated on its own merit. What are the pros and cons of eco-friendly soap? That’s what we should consider, not your distasteful body odor. That’s why this argument commits an ad hominem fallacy.

However, consider my original statements.

You’re an idiot. Even if we care about nature, banning fossil fuels would lead to massive deforestation as manufacturers turn to biofuels as a substitute. So we shouldn’t listen to your smooth-brained policy proposal.

Notice that even though I am calling you an idiot, and even though I label your proposal as smooth-brained, I’m not saying that we shouldn’t listen to you because you’re a smooth-brained idiot. I rely instead on the effects of banning fossil fuels to support my conclusion. My comments on your lack of intelligence are simply fun add-ons that don’t play a logical role in my argument. So I’m not committing the ad hominem fallacy.

Environmentalist: Interesting. I think I get it.

Philosopher: Let me give you another example.

Environmentalist: Thanks, but I’m pretty sure I und–

Philosopher: You’re a stinky, mouth-breathing dunce. Ad hominem?

Environmentalist: …Yes?

Philosopher: Ha! Trick question – it wasn’t even an argument. So calling the claim logically flawed wouldn’t even make sense.

Environmentalist: I see. Well, I have to get–

Philosopher: If I had said, for example, that we shouldn’t listen to you because you’re a stinky, mouth-breathing loser and nobody likes you, then that would have been an ad hominem fallacy.

Environmentalist: Thanks, I got it.

Philosopher: You’re welcome, you foul-smelling fool. Not ad hominem!

That sounds like a god plan. You could also do 1 LR section every week or every other week (followed by thorough review of that section).

You might want to check out some of the Fast Track lessons -- https://7sage.com/lessons/logical-reasoning (scroll to the end of this unit). I don't think you need to push through the entire curriculum. But as weaknesses show up based on your PT/section review, you might return to specific parts for a deeper dive.

I'd proceed to RC, but feel free to do an LR section every week as you work through the RC curriculum. Or, if you already know you're weaker at certain LR questions, do a few drills of those questions every week.

Moralist: Closing this factory would destroy 500 jobs and devastate families. We therefore should keep the factory open.

Environmentalist: Ridiculous. Merely pointing out negative consequences of the proposed factory shutdown does not prove we must keep the factory open. You’re overlooking potential benefits! This shows we should proceed with the factory shutdown.

Moralist: Pure nonsense. Obviously I know that I should have considered potential benefits and established why the costs of the factory shutdown would outweigh those benefits. But the fact that my argument was inadequate to prove my conclusion does not show that my conclusion was wrong! So your own response is flawed when you conclude that we should close the factory. Given your fallacious response, it’s clear that we should keep the factory open.

Environmentalist: Foolish hogwash. You’re the one committing the “fallacy fallacy”! Even if my own response was flawed, that doesn’t prove that we should keep the factory open. You can’t just reject my conclusion because my argument for closing the factory was a weak and unpersuasive criticism of your own argument for keeping it open. This is why the right course of action is to shut down the factory.

Moralist: Utter codswallop. Yes, perhaps I committed the “fallacy fallacy,” but the conclusion of my fallacious argument could still be true! What reason have you given for proceeding with the shutdown? None. All you’ve done is criticized my own argument against the shutdown. Hence, we should keep the factory open.

Concerned citizen: Please, just stop! Don’t you hear yourselves? You’re both committing the same fallacy over and over. Moralist, if you want to argue in favor of keeping the factory open based on the costs of a shutdown, you should show that you’ve considered potential benefits and that they either don’t exist or are outweighed by the costs. And Environmentalist, if you want to argue that we should proceed with the shutdown, you should tell us about the benefits of the shutdown and why they outweigh the costs. Tearing down each other’s arguments doesn’t build up your own. That’s why you’re both wrong. We should neither close nor keep the factory open.

Moralist and Environmentalist: Absurd drivel. Pointing out that our arguments were flawed doesn’t prove that our conclusions were false. That’s why, contrary to your absolute bilge-water conclusion, we should both close the factory and keep it open.

Note for students:

I know a lot of people don't like getting recommended questions that they got correct. However, resist the urge to select only the "Incorrect" option (or only the "Incorrect" and "Skipped" options). If you leave only the "Incorrect" option flagged as recommended for BR, then you'll automatically know that every question marked for BR is something you got wrong. That means you'll know that you should switch your answer. Often you were only down to two answers anyway, so you'll know that you should switch your answer to the other answer you were considering...and you'll get the question correct on BR without actually understanding anything about why the answer you picked was wrong and the correct answer is correct. This is not just a completely useless form of BR, but it's actually harmful, because it gives you a false sense of improvement.

TL;DR - Don't select only the "Incorrect" option or only the "Incorrect" and "Skipped" options. You WANT to have some questions you got correct recommended for BR so that you don't immediately know that you should switch your answer just because it's recommended for BR.

That's right. Paul must enroll in exactly one of those two classes. So if he enrolls in one, he can't enroll in the other. And, if he's not enrolled in one of them, then he must be enrolled in the other.

Go to Analytics --> Questions --> search for the question you're interested in by PT#S#Q#

You can also view explanations in the context of a drill/section/PT you took by going to the "Explanation" tab in the top right of your screen when you're in "Review" mode.

Yes, this is planned. Access to the older PTs should occur within the next week or two, with text explanations to follow shortly after.

To answer your question directly -- you can disprove a conditional by showing that the sufficient condition can be true, even if the necessary condition is false.

"A requires B."

How do we show that's false? By showing that A is possible without B. If A is possible without B, then A does NOT require B.

Does that help you understand why D weakens?

Also, I'll note that you aren't wrong, on a first glance, to think that "the painters must have needed....." is a fact/premise that we should accept as true. However, there are some rare cases in which the LSAT does present us with answers that weaken by suggesting a premise is false. This is arguably one of those cases. One signal that "the painters must have needed..." is particularly susceptible to questioning is that it's a speculative statement -- "must" in this context suggests the author doesn't know that the painters needed to eat sea animals, but rather is speculating that this is true because it sounds reasonable.

Follow the rule for unless. Treat the "no" as a negation of the concept it's connected to:

No X unless Y.

The two parts: [No X] and [Y]

You negate one of those parts, make it the sufficient condition.

If NOT Y --> NO X

or

If X --> Y

So your diagram is correct -- it looks like you intuitively applied the unless rule in the way I described above.

Do you think you have enough time for those? Many of those questions can take over 1.5 minutes, some even over 2 or 2.5. If you don't have enough time for these, that can contribute to mistakes here. That's why you can often improve at the harder questions by practicing going faster through the first half of a section.

We're currently working on getting some more granular tags so that it's easier to identify truly similar questions. Right now, one "Weaken" + "Causal Reasoning" isn't consistently similar enough to another one with those tags that you'd reliably benefit from seeing those questions together. Once this extra tagging is done, we'll be able to show you very similar questions.

Regarding whether you'd need to manually search for similar questions in the drill creator (or questions page) -- what are you thinking would be most helpful? A list of similar questions you might click to as another tab next to Explanation, Analytics, Discussion? Being taken to a drill of 1 or more similar questions? Something else?

Could you help me understand what you mean by this:

"the argument never says SOME claims are inaccurate, instead it says THE CLAIMS ARE INACCURATE."

As I understand it, if the author thinks the salespeople's claims are inaccurate, isn't it true that the author thinks "some" claims are inaccurate" Remember, some means at least one. So the author is asserting that at least one claim is inaccurate (in particular, at least the claims made by salespeople concerning teh quality of the products).

Premises are the claims the author offers to help prove the conclusion. So if you're not sure whether something is a premise or context, you could ask, "Why does the author believe the conclusion is true?" If the line you're considering isn't part of your answer to that question, it's not a premise.

In addition to the great advice of @haena and @, I'd encourage you to spend even more time reviewing your mistakes. You're probably getting enough wrong on each PT that it should take at least 10 - 15 hours just to break down and deeply understand all of those mistakes. It's not enough to just look at the short written explanations or to browse the video explanations -- do you understand your mistakes well enough that you could write out exactly what you did wrong and what you were supposed to do/think? Can you write out a step by step explanation for how to get to the correct answer for all of those mistakes? Hold yourself to a high standard of understanding. There's no point in taking another PT unless you've done this kind of review for the previous PTs.

Also, from looking at your analytics, it looks like you're trying to finish each section and spending about the same time on each question that someone who's in the 160s or 170s would take. That's the wrong approach right now -- you'll get a better score and improve your understanding of the test if you forget about trying to finish each question in the 35-minute limit. Your skills just aren't there yet -- forcing yourself to try to answer every question guarantees that you'll read too fast, misunderstand arguments, pick answers without fully thinking them through etc.

Are you sure?
