0:00Hey there , my little grasshopper ,
0:02Professor Maichael here . You're at
0:03Praticando Matemática , your math
0:05channel for civil service exams . The
0:07Transpetro notice is out , all right ? We
0:10know it's a high school level exam , it
0:12has math , and there's a video here on
0:14the channel talking a bit about this
0:15notice . And now I want to talk to you
0:19about the following : what should we
0:21focus on in the final stretch , Maichael
0:23? Is it possible to try to cover the
0:24entire syllabus ? The syllabus isn't
0:26huge , you can certainly cover it well ,
0:28maybe even finish it all , depending on
0:30your availability . And I want to show
0:33you in this video the topics that
0:34Cesgranrio likes the most , what the
0:36board loves to test . So you can pay
0:39close attention , it's a detailed X-ray
0:41in this video . So hit that like button
0:44right away , deal ? And it's also worth
0:48remembering : many people want to
0:50neglect math and Portuguese , saying , "
0:52No , what will determine the ranking is
0:55specific knowledge and blah blah blah . "
0:59And yes , man , in the first cutoff , what
1:01makes you qualify is the specific
1:02knowledge . Most will do well in the
1:05specific subjects , especially in
1:06technical fields , even those with only
1:08a high school diploma , because specific
1:10subjects are where people usually have
1:12more ease . However , once you qualify
1:15with the specific score , to then enter
1:17the final ranking , your Portuguese and
1:19math scores come into play . So
1:23Portuguese and math can literally get
1:26you into Transpetro ; it will be crucial
1:28after the first cutoff . So you cannot
1:32neglect it . And we know math is
1:34historically a headache for many people
1:37. Comment below if you're afraid of
1:39math , follow the channel , there will be
1:41a playlist of lessons here for
1:42Transpetro , don't let the enemy win ,
1:44okay ? So let's go . Without further ado ,
1:47man , what did I do here ? I analyzed ,
1:49right ? I analyzed 730 Cesgranrio
1:53questions from 2013 to 2023 , alright ?
1:59Out of these questions , based on the
2:01topics in the syllabus , those 10
2:03syllabus items , we have 459 questions
2:05there . What did I do with the syllabus
2:09topics ? For the 459 questions , I
2:12created a ranking for you to understand
2:15. So , observe what Cesgranrio really
2:18likes to test . Numerical sets and
2:21operations by a long shot . 26.4 % . Then ,
2:26ratio , proportion , and rule of three ,
2:2923.8 % , and the topics of plane geometry
2:31. So , see , if you're smart and you
2:34master , for example , this part here ,
2:37you guarantee , well , guarantee is a
2:39strong word , right ? But based on the
2:43logic of what the board likes , you can
2:44achieve a success rate of close to 40 % .
2:48Do you agree with me ? And then you
2:50follow the other topics here , look .
2:52Look , equations and systems , number
2:54sequences that aren't in the syllabus ,
2:56then functions , statistics ,
2:58combinatorics , geometry , probability .
3:01This , by the way , is a very interesting
3:04guide for you to emphasize what really
3:07matters when you're studying , okay ? And
3:11it's worth remembering , you might be
3:12asking yourself : " Man , Michael , I want
3:14to have this X-ray study guide you're
3:15using in this class . How do I get this
3:17study guide ? " I'll tell you more than
3:19that , okay ? You can get access to this
3:22study guide in the following way . Our
3:25group , our Portuguese and Math group
3:27for the secondary level exam , is that
3:30cool ? The complete Math and Portuguese
3:33course is open . And look , it's only 97
3:35Reais at the moment I'm making this
3:37video , the Math and Portuguese course
3:39for just 97 Reais . You will have all of
3:43Portuguese explained from scratch , all
3:44right ? All the math explained for you
3:47from scratch . There's artificial
3:49intelligence to answer your questions .
3:51We teach you from basic arithmetic ,
3:53with solved lists and videos ,
3:55everything nice and neat . And besides
3:57that , what did I put in as a bonus , man
3:59? I included study guides here . In
4:02these study guides , you'll have the
4:03X-ray , which is the one I'm using .
4:06You'll have math practice question
4:07guides . So , these math questions are
4:10fully solved and commented on for you
4:12to practice . You'll have the Portuguese
4:14X-ray and you'll also have the X-ray .
4:16You'll have the Portuguese X-ray and
4:17you'll have the Portuguese practice
4:18question guide as well . At the time I'm
4:20making this video , it's not here yet
4:22because I'm finishing it , okay ? But the
4:24complete Math and Portuguese course for
4:27you has , as a bonus , this PDF I'm using
4:30here to teach this class for only , man ,
4:3397 Reais , people , for God's sake . 97
4:35Reais for you to study the topics that
4:40can get you qualified . Don't let the
4:43enemy act , the link will be in the
4:45description , okay ? So , following the
4:47analysis here , man , what do I want you
4:48to pay attention to ? We have the
4:51percentage there , it's a really cool
4:53thing , okay ? But here I've estimated 10
4:58questions on the test by analyzing
5:01recent weights , okay ? From 2021 to 2026
5:05, okay ? All right ? Because the board
5:07has really changed its style . We even
5:09have a chart here that shows a bit of
5:11that change . So , what is likely to
5:15appear on this test ? Uh , two questions
5:19involving rule of three , proportion ,
5:21percentage , or ratio . Two questions
5:25that will manipulate equations and
5:27systems , one or almost two on sets . So ,
5:30do you see this ? This is how the board
5:32has been behaving and how it should
5:35distribute this . So this also gives you
5:38a great guide on what you need to focus
5:39on , all right ? Notice that the board
5:42has changed things up . Look at this
5:44cool thing on this chart here too , man .
5:46Look at this cool thing . If you take
5:48the period from 2013 to 2018 , it had
5:50one look . And then when you take the
5:53more recent period from 21 to 26 ,
5:55because for example , you might take a
5:57Transpetro test , even an older
5:59Transpetro one , you'll encounter a
6:01different assessment pattern than the
6:03most recent one . Are they good
6:05questions to practice with ? Yes . But
6:07you always have to understand that the
6:09test started to change its style a bit .
6:11Look , the gray is the old behavior .
6:14Notice that a quarter of the test was
6:16basically these topics . Now you have 20
6:19% , which is one-fifth . Sets and
6:21operations were 30 % , in the more recent
6:24period it's 16 . So you see that in the
6:27more recent period it likes ratio ,
6:29proportion and rule of three , sets and
6:30operations , equations , systems . But
6:33look at how the weights have been
6:34changing here , look . Look at plane
6:36geometry which was 20 % , now only 10 % .
6:38Look at functions which were two , and
6:39it was eight . See ? There's a growth
6:42trend too . Functions are growing ,
6:44combinatorics are growing , statistics
6:46are growing . And you need to keep an
6:48eye on this , all right ? What's going up
6:50and what's going down . This is the test
6:52trend . Another cool thing is the DNA of
6:56the math prompt . How does the board
6:59like to frame the questions ? 71 % of
7:03Cesgranrio's questions involve a story
7:07or a real-world context . So , possibly
7:11on the test we'll come across quite a
7:14few questions involving concepts of
7:16daily life or even things involving
7:18Transpetro itself , all right ? 18 % of the
7:22questions will bring units of
7:23measurement for you to work with , among
7:25them the most standard are kilometer ,
7:27cubic meter , kilo , and liter , okay ? 16 %
7:30involves money in the prompt , all right
7:34? 14 % depends on a figure , all right ?
7:38and tables and charts 3 % each . Nice . So ,
7:42interpreting the prompt text , well , pay
7:45attention because this will be crucial .
7:49Interpretation , interpretation will be
7:54key in the exam , all right ? That’s
7:59why in our math course we go step by
8:01step and have a module just to help you
8:03interpret questions , all right ? Very
8:06carefully . Got it . Seven questions . Uh ,
8:09the important characteristics are in
8:11the DNA of the characteristics , all
8:13right ? Here , subject by subject . And
8:17here we have something , man , very cool
8:19in this document , which are the tips .
8:22Inside , for example , plane geometry ,
8:24what do they like most ? Perimeter and
8:27area , then rectangle and square , see ?
8:30And Pythagoras in a context with famous
8:32Pythagorean triples . All right ? Uh , for
8:35example , here in basic statistics , what
8:38does the board like most ? Simple
8:40arithmetic mean and weighted arithmetic
8:42mean . So , this document is very
8:44detailed , man . It gives you a real
8:46guide , a real analysis of what the test
8:48likes most . All right ? Awesome . And
8:52then , what is important here ? It's also
8:54worth checking out what the board
8:57doesn't test . What don't they test ?
8:59It’s worth looking at . It’s
9:01what’s in the syllabus and is very
9:02rare . So , when you're in the final
9:04stretch , uh , we can consider that with
9:06the syllabus published for the test ,
9:07you're kind of in a race against time .
9:10So , this stuff that they almost never
9:12test , it's very important to keep an
9:13eye on so you don't waste time
9:15foolishly , okay ? All right ? Spatial
9:18geometry . Uh , let's see some model
9:22questions here for you to understand .
9:25For example , here , look at this
9:27Transpetro 2023 question . See , look ?
9:30Area and a story , okay ? All right ? Look
9:33at this other question . A consumer went
9:35to the market with 1 kg of potatoes , 1
9:36kg of onions . Look at this question
9:38here . Triangle ABC is a right triangle .
9:41So there will also be some questions
9:42here for you to solve . We will have
9:45here , on our channel , man , resolutions
9:47of the board's questions , reviews of
9:49the board's questions . It's very worth
9:51it . If you want to have more classes ,
9:54follow the channel here , all right ?
9:57because I'll bring a lot of content if
9:59you guys enjoy Transpetro math , all
10:01right ? Just a reminder , if you want to
10:03join our math class in Portuguese ,
10:05covering the basics of high school
10:07level math , the link is in the
10:08description , it's only 97 Reais . It's
10:11honestly bizarre , man , offering a
10:13course with this kind of quality . Look
10:15at the PDF I just showed you , plus the
10:17video lessons , man , so you can truly
10:19unlock areas that most people won't be
10:21looking at , okay ? And let's go together
10:24. Other videos about this content will
10:26appear here on the channel . I'll bring
10:28math classes solving Gran Rio questions
10:30. I hope you liked it , and enjoyed it .
10:32May God bless you . See you next time ,
10:34and I'm out .
