I think it's a typo and they meant 60 degrees not 90 degrees.

If the arc measure of arc AB was 60 degrees, then arc AB would be equal arc AC and arc BD. In this case, chord AB would be equal to the radius and QA = 1/2.

However, it states that arc AB is less than arc BD, so its arc measure must be less than 60 degrees. Thus, chord AB is less than the radius of the circle and (chord AB) / (chord CD) is less than 1/2.

I really want the answer to be extrapolate because it sounds good. But unfortunately, it is not the correct answer.

The phrase "conspiracy against" means someone or something is asserting influence over language. Only Answer Choice E is appropriate as manage also means "to assert influence and control over."

Sounds like you already know where you need to focus your study which is good.

It wouldn't be a bad idea to spend most of the study time you dedicate to verbal focusing on learning vocabulary. If you have enough time in your prep, just targeting vocab while you improve your quant skills would be a good idea.

However, it might be worthwhile to include a few study sessions a week doing questions in order to avoid getting rusty.

I think that they are developing a theme, and that theme is about Padgett being contradictory. The first sentence is just an introduction to the theme, so they don't talk about her business-related etiquette. They then elaborate on this etiquette in the sentences that follow. So you are right!

In the first sentence we learn about how colleagues view Padgett's antithetical nature. This concept is repeated in the second sentence where they describe how this nature is reflected in her business behavior. The third sentence provides evidence for Padgett being prone to contradictions in business.

She does not dispel the contradictions that her colleagues impart on her, because her business behavior is also full of contradictions. So she actually does a lot, not a little, to fulfill or accentuate what her colleagues think about her. That is why dispel is the correct answer.

I hope this helps. If you need further clarification or have more questions, please let me know.

I believe if you search for them, the problems can be found for free online. While I cannot officially recommend doing such things, I can understand why those with limited financial means might do so.

I'd still recommend taking at least one of them if you can spare the cash. After all, 40 USD is a lot cheaper than the 200 or so you need to shell out for the actual test. The PP+ tests are the closest thing to the real GRE and are a great way to assess your readiness for the exam.

Good luck on achieving your 170 in Quant!

You can try the Problem Solving questions from the GMAT Official Guide and Quant Review.

I think they would best be used by randomizing all the problems in an excel spreadsheet and then making 15 question practice sets to emulate the second, hard section of the GRE. Make sure to time yourself for 26 minutes.

There won't be any Quantitative Comparison questions to practice as the GMAT has Data Insights instead. For those, you can check out the Powerprep+ practice tests.

Indeed. And that's what is cool about math. There are often many ways to the same answer.

Using Difficult-Way's logic, I think you could choose the 10 different dates with 365C10 then order them with 10!/356^10. That would lead to the right answer.

But I think using permutations like you and Greg used is much more straight-forward.

My recommendation would be to do all the verbal questions from the ETS books and the Powerprep tests, both paid and unpaid. Analyze the problems you got wrong, figure out why you got them wrong, and find the evidence in the sentence or reading passage that justifies the correct answer.

Also, do the vocabulary mountain on Gregmat. Go through all the tests and keep track of any words that you either got wrong or didn't know immediately. Put these in a flashcard app like quizlet or anki and review them until you know them all.

The verbal strategies from Gregmat should be helpful too, especially for reading comprehension. But in my own personal opinion, things like the math strategy or support/contrast might not be as necessary for a native English speaker. I found that these concepts are more intuitive and less explicit, at least when comparing myself to non-native speakers.

This is not to say that they aren't good strategies and they may very well be helpful. I both study and practice them to help my students / mentees.

What's your timeline for completion, that is, when do you want to take the GRE?

I think a good idea would be to go through the TTP course fully and do so in order to build your quant skills. You can use Gregmat for quant strategy and apply these strategies to the quant problems in the chapter tests.

Good Gregmat videos to watch would be "4 keys to high quant" and "The Tick Box Method." For the Tick Box Method, you would want to find videos that go more into the quant strategies in depth. I am not sure if such videos are on Gregmat, but I they are definitely on Prepswift which is only 2 USD extra?

In this case we don't need to, because according to the question, it only matters that the number is odd and prime. It doesn't matter whether that odd, prime number is a 3 or a 5. The wording of the question will help you figure out what calculations you need to make in order to get the question correct.

However, I'm not sure I can help with your hypothetical probability problem. But if you post a screenshot of the kind of problem you're thinking of, I'd be happy to help explain it.

Finally, I am definitely familiar with the feelings of confusion that comes with learning new math concepts and going into uncharted territory mathematically in your mind. I think here, mindset is important.

Instead of thinking it as something confusing, perhaps try thinking of it as a puzzle you are trying to solve. You may not be able to fully grasp the concept from one problem, but that's ok. You just haven't gotten enough familiarity with it and in order to get familiar with it, you have to do more problems.

And make sure not to let the fact that you're getting a problem wrong derail the learning opportunities you get because you got the problem wrong. You are just finding another piece of the puzzle for full conceptual understanding.

If ur having trouble with a combinatorics problem, or in this case, the combinatorics part of a problem, a little bit of brute force can be helpful.

So let's just list all the possible ways we can have five dice rolls where three of numbers are both odd and prime and the rest are not:

Let P = an odd prime number

Let N = a non-prime or an even prime number

  1. N N P P P

  2. N P N P P

  3. N P P N P

  4. N P P P N

  5. P N P P N

  6. P P N P N

  7. P P P N N

  8. P N P N P

  9. P N N P P

  10. P P N N P

So there are ten ways that the we can roll three odd prime numbers in five dice rolls.

But writing all that out was pretty time consuming and kind of made my brain hurt. So it's much easier to use combinations. If we represent that big list as 5C3 instead, it would be much easier to calculate:

5C3 = 5! / 3! (2!) = (5*4*3*2*1) / (3*2*1)(2*1) = 5*4 / 2 = 10

Hope this helps and let me know if you have any questions.

Have you tried skipping through the questions during the test / practice set?

Some people have success starting with the questions they find easier and moving on to the more difficult questions once they have built confidence solving the easy problems.

The Powerprep+ mocks are closest to the actual GRE.

Who do you think would make better practice exams: the company that actually makes the test or a third party company that hires GRE tutors to make their material?

Do you have any plan to take the Powerprep tests?

You should at least do the two free ones and then afterwards do all the questions in the easy, medium, or hard sections that you didn't get.

The free practice tests are a bit easier than the actual GRE though, so keep that in mind when assessing your readiness for the actual exam.

They are indeed. Always be wary of their tricks and traps.

On the GRE, geometric figures are not drawn to scale. So the angle RST could be acute, right, or obtuse.

Since we are unable to determine anything about that angle based on the given information, the relationship between RT^2 and ST^2 + RS^2 cannot be determined and thus the answer is D.

Hopefully, this helps clarify things.

It depends on the level of accuracy you desire.

If you want something more accurate, then the free Powerprep from ETS would be best. However, PP1 and PP2 are a bit easier than the paid Powerprep tests or the actual GRE.

If you just want a general idea of ur abilities, a third party test would be fine. Since your are doing Gregmat's plan, it might make sense to take his practice tests and save the Powerprep tests further down the line.

If their customer service people don't speak English, then it is unlikely they will have created an English version of a document that was made for Chinese students.

In my opinion, translating the document would be a waste of time. While I would recommend it to a native Chinese speaker, the information provided can be found elsewhere.

If there are specific parts of the pdf you would like translated, I would be happy to do so if / when I have time. I can also tell you what to say in Chinese if you wanted to ask their customer service staff to confirm that their isn't an English version of the document in question.

I speak the language fluently and I'm not sure it would be that helpful to anyone but a native speaker of Chinese.

I looked it over and it seems to be just Chinese translations of GRE-specific English words as well as foundational material that can be found in the ETS Math Review: https://www.interactive.onlinemathlearning.com/share/ets/gre_math_review.pdf

Formulas are also included in the Chinese document and can be found here: https://drive.google.com/file/d/1m-zXAQ-wdlbNAR2SO3-KfAN_MZ8XftAP/view

Given the nature of the document, I do not think they have an English version. But if you need assistance contacting them in Mandarin, please let me know.

What is its name in Chinese?

I like quizlet personally, but I have heard that anki is very good too.

The only downside is having to create the cards yourself.

You can simplify but you can't cross multiply. We don't know if x or y is negative or positive.

Since the quantitative comparison is potentially an inequality, we cannot multiply the opposite side by a negative number otherwise it would reverse the inequality making the comparison impossible.
