I think you should check that with your PA teacher, just to be safe. Your teacher is the one who is going to evaluate your PA pembentangan after all, but nevertheless I think Just Visiting By can give some vital advice. Just so you know that my PA teacher advocates us to do a mild comparison on the topic itself, like, Perbezaan adat resam dalam perkahwinan antara upacara perkahwinan kaum Cina dan India, or Perbandingan proses pembuatan makanan tradisional antara mee kari putih dan mee kuning, but little did I know that we can also make a comparison out of our lokasi kajian....

Boy, you're not the only one who got yourself in this quagmire. We're required to hand in our PA coursework by this Friday(I'm required to submit 2 kerja kursus), and so far all we've been doing during PA lesson is only working on our kerja kursus, ergo our progress in studying all the Dasar-dasar and graph drawing is stagnant. The thing is, I think you need some rest for the moment, you know that you can't perform at your best if YOU are not at your best. Try to get your teacher to give you a little time to recuperate before you get back on the track. As for my classmates and I, our daily average sleeping time is at 2 am till 5 am, roughly 3 to 4 hours per day. And that is already considered a norm for us.

Thanks RED_HAIR_SHANKS

BTW I have asked my PA teacher, as expected, she gave me a NO for doing two locations for PA coursework.

Can I ask you regarding MUET? Is the trials in the school determines your real performance in MUET or it will be better?

Just Visiting By, for drawing graphs in PA, how to identify the keywords in the questions so that you won't do the wrong graph? For instance, keywords like 'perubahan' is line graph, but if there is 'kadar perubahan' or '....antara...' then it's Bar Graph. I am so confused...

The mixture being hypergolic is only part of the picture. In the early days, all manners of propulsion were being dreamed up. This included nuclear powered space shuttles, but that was ultimately scrapped. Combustion engines are some of the more developed technologies, but these engines are complicated and there is no oxygen (well, air) in space, unless one intends to carry a large amount of oxygen into space. So ideally, there would be a chemical A, that when exposed to another chemical B, would release large amount of energy.

The methylhydrazine and dinitrogen tetroxide mix is one such example. They don't just react, they react vigorously (imagine if they don't). They release a large amount of heat per unit mass, and they are in liquid form (gases take up large volume of space unless compressed, a difficult feat in space, and solids just don't react as readily). Another advantage is that the products are water, nitrogen and carbon dioxide.

The 20℃ is there because that is how data are usually given. Solubility is a tricky thing. You can predict a trend based on some rules, but there's no guarantee that everything will fit.

LOL I am sorry I can't really remember.

It has been a very long time since I last studied PA.

I can remember the strict requirements but I can't remember the keywords to look for.

All I can tell is that whenever the question is not specific, graph bar is always favoured over graph garis.

Just a quick question here concerning PA graph:-
Suppose that I get a question that has passages which sound like this:''...kadar peningkatan penduduk Cina meningkat kepada 20 ribu pada tahun 2007...'' or ''...jumlah penduduk bumiputera dalam tempoh 5 tahun tersebut hanya meningkat menjadi 120 ribu pada tahun 2012...''. Now, if I were to plot the y-axis of the graph, should it be like 20000, 40000,60000,80000... for every 2 cm, or 20, 40, 60,80,... for every 2 cm and finally add a ('000 penduduk) when labeling the y-axis?

And having said that, what should we write for our skala? 1 cm:10000 penduduk, or 1 cm: 10 ribu penduduk?

I would prefer the former, where you label the y-axis as 20,000, 40,000....Alternatively, you could label the unit as bilangan orang (ribu), and then label your y-axis as 20, 40, 60...

On skala, it's safer to write 1cm: 10,000 penduduk.

Thank you for your brief explanation. It's enlightening for me to find out that by simply getting a fuel,methylhydrazine coming in contact with the oxidizer,dinitrogen tetroxide, both propellants will easily ignite. And since both methylhydrazine and dinitrogen tetroxide are already in liquid state at room temperature, it comes to show that hypergolic propellants are easier to be stored compared to cryogenic fuels, since the latter need to be kept at a very low temperature in order to preserve their liquid state,no?

Thank you.

Krevaki, I got a tiny problem here. So this is the question:

But the answer that got was π-2, and not π+2. This is my working:






Did I make any mistakes in my calculations?

I don't quite get it on what you meant by ''it will be better'', but, as far as I'm concerned though, it all depends on the nature of your MUET trial questions. If you feel that most of the reading questions from your trial are far more challenging than those model tests/practices from revision books, then I guess it's safe to say that your MUET trial papers could be a reliable indication on how you'll score in the real test. But again, this question seems subjective and since I never do your MUET trial papers, I can't reassure you whether your past performances in trial could be better than your real test in March.

The reason on why I'm emphasizing on reading section is because it is unequivocally the most important(and crucial) section out of the 4 components due to it's higher weightage. Based on my past experiences, nearly all of those reading practices, books and exercises that my classmates and I had done in the past are extremely easy, and on recurring basis, we would score 42 to 43 questions out of the total 45, even under the 90 minutes mark. But boy, when it comes to the real MUET reading component, it was a whole new beast. I failed to complete all the questions in time, leaving 8 questions blanked. As for the other 2 components(Listening and Writing), all you have to do is keep on practicing with all of the materials that you have in your arsenal, and you'll be good to go.

While we're on it, I suggest you to try out as many past year reading sections as you can. Go look them up in the internet. And if you haven't done it yet, I urge you to try the MUET Paper 3(Reading) 2012 November session. Personally, it's much much more challenging than the real paper that I had in my exams last year(2014 November session).

Your answer is correct.

Alright, I guess my answer is correct after all. I tried to redo my workings by making a little tweak here and there, and still my final asnwer is π-2.

My second working:

This is my STPM 2014/2015 first term result:-

Subjects, Grade, GPA:

PA, C, 2.00

Maths T, D, 1.00

Physics, B-,2.67

Chemistry, C, 2.00

CGPA: 1.92

I expected it to be worse(at least CGPA of 2.00), but I never thought it to be this worst!! I'm not gonna dwell on it since my second term exam is approaching, not to mention I'm going to be retaking my first term in this November anyway.

Oh, Just Visiting By there's another thing here that I want to clarify on behalf of my friend. How do we calculate his CGPA since he took 5 subjects in his first term exams? His results are shown below:-

Subjects=GPA

PA=3.33
Maths T=2.00
Physics=4.00
Chemistry=3.67
Biology=3.00

Thanks.

Pick the best four then sum it up and average it.

It's okay, try again in your second try. I haven't checked mine, and I think mine is worse than you.

My results PA, B, 3.00.

Maths T, B-, 2.67.

Chemistry, A, 4.00.

Biology, F, 0.00.


Kinda surprised I managed to scrap a B for PA because I skipped out on the subjective questions entirely and tembak randomly for objective as I spent waaaayy too much time on my essay. (Bad time management, always comes back to bite me in the ass during crucial times.)

And yes, you read that right, F for my Bio. This is fucking humiliating for a Bio student. I don't even know why I took Bio when I'm unwilling to study for it. I didn't even finish reading the Sem 1 Bio textbook, much less do revision for it. I made a huge mistake when choosing which subjects to take, and it seems that this mistake is probably going to ruin my life. Should have just gone to IPG and become a English teacher like my parents.

@RED-HAIR-SHANKS, also, no offense but do you suffer from anxiety attack during exams? Your Maths T is evidently way better than mine as I've seen you solve many MT questions on here when I can't even figure out the right formula to use for them.

Just asking because there's a guy in my class who never failed to solve every single question thrown at him during exercises, but during exams he just freaks out and have never managed to score an A in Maths T so far despite knowing how to solve every single question in the textbook.

Oh, I see. But, I've heard it through the grapevine that if one were to sit for 5 subjects, he/she has to include PA into the equation and pick the other best 3 results. Can you verify this for me?

Worse? Please, don't insinuate yourself in that way. I might not know much about you, but after I've done your Malacca High School trial papers, I found out that mine are jokes compared to yours. And yet, I still failed every subject in my first term trials. You've come a long way now and you've been consistent in your studies.

I've gathered up most of the results of my class, and for your info, I scored the lowest in both Maths T and Physics. In our Physics class, there are a handful of students scoring 4.00 GPA(the highest) and I'm the only one scoring B-(the lowest). And if I'm not mistaken, for Maths T, I'm the one and only student who scored 1.00 GPA(the lowest) for that subject. I can't give much comment on the other 3 subjects due to lack of information.

This is depressing, I am embarrassed. This is utter humiliating...

No. Don't underestimate yourself. Failure once doesn't mean you fail in your life. I understand your situation, because it's a pain in the ass when you are pointed down when compared with your classmates.

MY RESULTS:
Subjects, Grade, GPA:

PA, A, 4.00

Maths T, A-, 3.67

Physics, A-,3.67

Chemistry, A, 4.00

CGPA: 3.84
