QUOTE(RED-HAIR-SHANKS @ Oct 23 2014, 04:05 PM) Critical_Fallacy, can you help me with this question?
Question: An object is thrown at an angle to the horizontal with a parabolic trajectory. PQRST is part of the trajectory with P as the starting point and T as the maximum point. If every two adjacent points have the same time interval, hence the displacements PQ, QR, RS, and ST A: are the same B: increase at a fixed rate C: decrease at a fixed rate D: have the same horizontal component
The answer for it is D.
−I used the formula of s=vt, and I find out that the horizontal displacements,s, for every 2 adjacent points are constant due to the fact that time intervals, t=constant, and the horizontal velocity, v=constant too. But, from the choices above, how do I distinguish the answers between A and D? They carry nearly the same meaning meaning, don't they? Displacements are vectors. And you know that the norms | PQ| ≠ | QR| ≠ | RS| ≠ | ST|. This reason alone is suffient to reject ( A).

Secondly, the concentration of aqueous ammonia varies with volume so you should take note of that. But for second part..... I am not sure. RED-HAIR-SHANKS Critical_Fallacy Can you please check for me whether my answer is correct or not.  it's ok.. thanks~

Hey STPM peeps. Who got take chemistry need help.
When electrolysis 1.00 / 0.1 / 0.01 / 0.001 / 0.0001 mol/dm3 of Potassium Iodide solution, what product I will get for these molar concentration?

Thanks for the recommendation, though I think that there isn't much time left for me to complete every single set of trial papers that I can lay my hands on. These are only for Maths T, let alone we have another 3 subjects... Speaking about maniac, I've did most of the Physics and Chemistry questions from Federal books, and I felt that most Section A questions from said books are extremely crazy compared to the new semester books like Oxford, Longman and Pelangi. I feel like want to puke at the end of the day after completing some of the questions (only SOME questions, not ALL)  . For some reason, whenever I think of any Federal books, I feel like wanna vomit after marathon them at the end of the night.

Why go do Federal's? == Just do Federal Physics objective and subjective will do. Essay questions are way beyond university level. I am now a first year engineering students using international textbooks and the exercise in it aren't even half the difficulty of the Essay questions. Those questions are 1980s STPM questions that are now no longer required in STPM. Objective and subjective are also tough but at least doable. Chemistry is okay, not really much tougher. So they're good exercise. Don't torture yourself lol exam is coming don't give yourself unnecessary pressure. This post has been edited by Just Visiting By: Oct 28 2014, 05:48 PM

Some questions (only SOME) in said books are quite simple to solve, but they do require a high analytical thinking skills as a requisite in order to approach them. I'm not trying to overlook other STPM book out there like Oxford, Pelangi and Longman. They too have good and concise notes as well as extremely challenging exercises. But, most of the types of questions posed by these books are monotonous, and the patterns are roughly the same with only some minor exceptions. Conversely, when it comes to Federal's, most of them are a tough nut to crack and we are required to twist our brain in order to get the solutions. I don't really know if I picked the right book or not, but, taking the fact that STPM questions are prepared by university lecturer into account, don't you think that it's quite safe too if we try a much harder level question that are out of the box?

The essay questions in the books are too difficult for STPM students to digest. Objective and subjective are good and encourage critical thinking but essay questions are way beyond what form 6 students could handle. Trying too hard to grasp the questions, according to my experience, would end up with most people wasting their time and still not able to do them in the end because the difficulty level is, as I said, way beyond what form 6 students could handle. I'm not discouraging trying much harder level questions but I personally believe there's a limit to where you should extend it. Essay questions in Federal are too much. Just do the objective and subjective, they are good enough.

Besides, time is now of the utmost essence and I don't think I have sufficient time to blaze through every exercises that I stumble across. Thanks for your advice and thoughts.

Thanks for posting all the trial papers, everyone.
I got Sam Tet Ipoh's Maths trial from my friend, but there's no answer for it. If anybody wants it i can scan and post it here
Please post if you guys have Bio or Chemi papers from other states too
Thanksss

I just do not want to see people making the same mistake a friend of mine did. He over-exerted himself and ended up suffering from minor depression. He got all reference books available did all exercise he could obtain, but because he over-exerted himself he ended up barely scraped the C border. He became withdrawn, didn't communicate with people, spent all his time in school burying himself in his books until one day he drew CH3-CH2-CH2-CH2-CH2 and named it as propane, and when we tried to correct him he became quite surly and irritated and didn't bother us. And he was fine before he studied form 6. Don't follow his steps.

You know, my experience at university so far is kinda humbling. After such a long break from school, I had to start relearning everything and I realise now that I barely understood how most things were derived during my SPM and STPM years, especially when it comes to everything that goes under the Maths umbrella. All just memorise formula ni and rote-learning. Granted, all that was good enough to excel in exams (because of the way they're structured), but now that I attempt questions that are designed to test your understanding, man, I sometimes question myself if I really deserved my past results haha. » Click to show Spoiler - click again to hide... « https://mega.co.nz/#!IIlmWQDD!aaG2xS9kCWlKp0d-j5WBnux0zQI5J86gT9juE7VgI84 That's a sample seminar question I got today. Might be basic stuff for you guys, but it was quite a revelation to me to learn how the cumulative distribution function is derived and all the other tidbits my tutor threw in for fun.

But it's really pity to see your friend who was willing to sacrifice many things in his life (like social aspects and entertainment) ended up abysmally in his academia, albeit the fact that he put on lots of work and effort in it. Your friend's situation contradicts the ones from one of my classmate. I've personally asked him on the study period that he did throughout his life in secondary school, and he told me that he studied not more than 3 hours per day, and yet got straight As in PMR and 7A+,2A in SPM. And this year, he studies Form 6 with me and even with a study period of merely 3 hours daily, he got a CGPA of 3.62 in his trials. And he is far more laid-back than anyone of us in the class when it comes to studying, and unlike most of us in the class, he doesn't burn midnight oil. Whereas for most of my classmates and I, we could hardly catch up to the rhythm of our studies if we do not pull an all-nighter even for a day in any week.

It's a matter of study smart, not study hard. Do not burn midnight oil, I must insist. I personally did not burn midnight oil as well as burning midnight oil merely gives psychological comfort, as if you're studying more, but the fact is your brain is already overload and you shouldn't push yourself anymore. Quantity does not equal quality. It is true in the method of studying.
