Why didn't you cut the 6/2 to 3. I mean why did you use 6/2,why not 3?

[@aybeesart]

I just did this practice test and dang was I shocked

[@kayanshah07]

will these questions be found on the oct paper sat?

[@ace_world.proudction]

i dont still understand the second aND THE THRID EITHER. AND I HAVE MY EXAMS

[@icsetrailblazers]

I just solved the 2nd one yesterday, and I fell for it.

[@MonarchTK_]

Bro that 3rd question is crazzzyyy

[@megalasivashankar]

Thank you so much for making me understand the second problem. I never really understood it and instead resorted to memorizing it. This is the first time I truly know the WHYs and the HOWs of this problem. Thank you so much.

[@JohnSAT]

Understanding the WHY/HOW behind each question is the most important thing. Great job!

[@taskinsaadman8105]

Thank you, John! I was really unable to grasp the rationale to the answer of the second one while practicing but now it all makes sense! Power of the number line!

[@youyanq]

The 2nd problem can be solved intuitively (without the mean calculation), as the frequency of the data sets for each corresponding interval is equal, and the difference across every interval is one (20-19, 30-29, 40-39, 50-49).

[@Sjdijdhshsjshe]

Explain more pls

[@youyanq]

​@@Sjdijdhshsjshe Basically, the difference between corresponding/matching numbers (numbers w/ smallest difference) in the two data sets is always 1. This means that for every pair of corresponding numbers between the two sets (e.g. 10 and 11) one number is always 1 unit higher (or lower) than the other. If the frequencies are the same for each interval (meaning for every value in one data set there's a corresponding value in the other), then each of these "pairs" contributes equally to the mean difference. Because every pair has a difference of 1 and they all contribute equally, the overall mean difference will be the same as that of any individual pair: 1. Example: You have two bags of apples with the exact same number of apples. If every apple in the second bag is just a little bit heavier (by the same amount) than each apple in the first bag, then when you weigh the bags, the second bag will be heavier by that same little bit, on average (mean). This should work (unless I'm proven wrong) for any time when the intervals remain consistent between the two data sets and the difference between corresponding values in the data sets is the same (regardless of the number). Of course, if the frequencies and/or differences were inconsistent across intervals, this intuitive method wouldn't work, but I doubt that would be on the SAT.

Hey John, I just wanted to say thank you. You’re videos are awesome and so is your formula sheet. And reading the emails that you send really makes me feel like you want your students to succeed. Today was my SAT and I watched your videos the night before and my math section had some questions related to the topics that you taught. I hope I get at least a 1400!

Thanks for the video! I got a 780 on the August SAT Math, and I'm trying to improve that even more.

[@turtlenation5636]

any tips on how you got that high of a score?

[@sidsingh9165]

@@turtlenation5636 Yeah so I took it again on November and I got a 790. So close to perfection! Anyway yeah so before that I would get like 720'2 on my math sat's so it was doable for me to make that jump. The main thing is to finish the test in time. I would usually spend time checking my answers and not having time to do the other problems so make sure you finish your section first and then go back up and check your answers if you have time so for now just make sure the answers looks right and then move on quickly. You also need a couple math concepts clear which I would recommend to use Khan Academy since they go over every topic on the SAT Math. Now the test itself won't cover all the concepts but Khan Academy will give you a good overview of what to know and expect. Once you have that basic understanding make sure to quickly take some practice tests. The 10 tests released by collegeboard are okay but I would prerfer to do the one's released by SAT QAS since they are more recent and officaly released along with the answers. If you do good on those tests then you should do good on the actual test so make sure to time yourself accordingly and whatever questions you see can be expected on the test. Some concepts like Geometery wihich khan academy goes into isn't as frequent besides trig so don't spend too much time on that. That's mostly all you should know. Just keep practicting, clearning concpets, and taking practice tests. That should help you out quite a bit. There's also a youtube channel you should check out which does some sat math problems: www.youtube.com/@mathster6703. Well that's all I have to say, I hope this helps.

[@hqs9585]

I have some issues with problem 26:If we plot both distributions in a single graph one notices that data B can have values from 10 to 19 with a frequency of 3, however the A graph can have values from 20 to 29 with a frequency of 3 as well. Hence the minimum value of the difference between A and B is 20-19 = 1 , this difference occurs with frequency = 3. Keep doing the same for each frequency i.e., 4,7 and 9; the result will be 23 which is 1*3 + 1*4 + 1*7 +1*9 =23. Now the average of this minimum differences for all frequencies is the sum over 23 samples. Average = 23/23 = 1. This rational makes sense. Yours doesn't. Sorry, good video.

[@JohnSAT]

you and I essentially did the exact same thing - except you found the difference first, then took the avg I took the avg first, then found the difference Both methods work. Whatever makes sense for you - stick with it.

Thanks so much for question 3, I gave it in the practice exams and had no idea how to solve it lmao, much appreciated. Could you explain the last 4 questions from each practice test on the digital SAT, they're usually the toughest.

[@JohnSAT]

will keep that in mind. glad it was helpful

[@sunjidaraisa6422]

For question 2 we could only just think of the histogram as a graph problem. Look at the graph it just shifted equal units for each bar we can take that as 1 unit and so the difference is 1 unit.

[@rishika66]

woah.

[@JoelJospeh]

[@dirknowitzki8744]

2nd question is just 20-19🙂 I did 1st too. Only couldn't do 3rd. Hopefully can get more than 680😊

[@vybsdeadly5493]

can you explain the reason for multiplying the number of integers between 10 and 20 (3) by 19 and so forth to get the mean. I just added up the largest/ smallest values, 19+29+39+49 and divided by 4 and the same for the other side ofc to minimize the mean so 10+20+30.... ik that theyre the same number of integers that are between 10 and 20 graph B and 20-30 for graph A. so multiplying wouldn't change the smallest difference because theyre both being multipled by the same factor of three, but what if it wasnt like that what if the graphs weren't essentially identical im guessing it wouldnt be okay to leave out the multiplying by the number of integers between 10-20 by the highest number 19, im guessing the multiplication is mandatory for every one of these problems?

[@saucegod5107]

I hope it’s not necessary because that’s too much work

[@tanvibadadare2622]

thank you so much!

[@JoyOnyekachi-p5f]

Hi please how did you get 887 in the second question... what did you add to get 887?

[@hayro6537]

Hello mr John Jung so i am going to take a SAT exam on November 4th and i take 3 bluebook full length tests i got 760 and 770, and now i am wondering did that test like real tests or those are easier that real, if you notice i will be very grateful ❤

[@placesexplorer8655]

you did the first one wrong check it again

[@JohnSAT]

no, you're wrong. It's solved correctly

[@TheSatSlayers]

what if they asked u for the largest possible difference in the 2nd question, would u maximize (or minimize) both of them?

[@Vluxxia]

how did you get 3,4,7,9 in the box for the 2nd question I understand everything else but not that

[@moogod]

Would it not be easier on 1 just to put the 2 equations in y=mx+b getting the slope of the top as 1/12 then knowing p=6 to make the slope of the second 1/12 making them parallel and have no solutions

[@无敌丸丸]

For first one, you can just make 2 equation have same slope but different y intercept, this is the definition of no solution

[@TheCollegeLad]

How many hard questions are in the module 2 when you got a perfect baseline score?

[@dannacastaneda4763]

why when you substitute 2 you put (94/47) instead of (92/47) for question 3

[@chsui4633]

About question 3, why did you choose to use the equation 2K, instead of just equation K?

[@chirmidetha4939]

Also in the third problem the rectangular prism surface area formula says 2(wl+hl+hw) on google. Why are we not using length measurements?

[@athulkollu8400]

you're gonna get the same answer either ways coz l=w

[@robinntas]

just need to ask in the first question can not we just set their slope same and solve that way?

[@WaleedHussain551]

how did 887 came at 5:28

[@Farah-yr2eu]

Hey I have a big problem I did horrible on the sat but when I looked on question I knew how to do it and I just did a small mistake or just did not read the question right or I just did not know what I was thinking at the moment and I already took all the practice sat what should I do

[@chirmidetha4939]

Why in the second problem we are using only one number from each category even uf their frequency says 3,4 etc. We should pick the numbers with frequency for the mean.

[@CrimsonDragon0801]

Will this be on the paper SAT too?

[@rodinecharles2367]

I dont understand the third one

[@Turnpike.]

Thank you for the video! For question 2 I feel like there's an easier way to do it; can't you just find out that the mean of both sets is just the 12th number since the sets have 23 integers, then whichever interval the 12th number is in you can maximize/minimize the value in their respective date set and subtract it and get the same answer. Just a thought

[@JohnSAT]

the median would always be the 12th number, but the mean wouldn't always be the 12th number. I can see your logic, but I personally wouldn't use it as it's too risky of a move, especially for students aiming for 700+. Appreciate the input!

[@Astroshid]

Hey. Thank you so much. Where is the link to these questions?

[@JohnSAT]

check the pinned comment

[@Analauraws]

in the 3rd question, in the system, how did you get 94/47?? (min: 9:00)

[@JohnSAT]

I multiplied the 2 by 47/47 to match the denominator. So 2/1 * 47/47 and multiply the tops and bottoms

[@Khan-w7v]

Sat math's section is very easy in the practice paper on bluebook, but some math's question are quite difficult on Khan Academy (DSAT) like in course challenge, does that kind of difficulty come in actual paper or it will be same as bluebook(difficulty).
