STPM Baharu In Depth - Chemistry (written by Li Tian Low)

This is an introduction of the subject Chemistry in STPM Baharu by my friend Low Li Tian, read on and you will get an idea of what you'll be learning for this subject in Form 6! 

 Okay , so I’ll start off with chem sem 1 first. Term 1 we’ll be studying about Physical Chemistry, well I personally didn’t like physical chem that’s why I didn’t have much “memories” bout it. Well, through this physical chem, u’ll be studying about electronic Structure of Atoms, chemical bonding , states of matter , reaction kinetics & equilibrium. Chapters about electronic structure of atom & chemical bonding r quite interesting but not for equilibrium (just my opinion). Overall , term 1 chemistry was quite easy , no memorizing work ,u just have to understand the concept.

Eg:  phase diagram for a single-component material, exhibiting solid, liquid and gaseous phases



Term 2: Inorganic Chemistry . The first 2 chapters r about chemical energetics & electrochemistry . So u’ll be learning different types of standard enthalpy changes of reaction & need to know how to calculate electrode potential. The rest of the chapters r periodic table , group 2 elements, group 14 , group 17 & transition elements . These chapters requires a lot of memorizing work, but don’t worry coz there r connections between the elements of different groups . Once u have to understand well, then It’s easy to memorize them. I suggest that u read a little everyday so that u can master these chapters easily .
eg : Nernst Equation.
R = gas constant
T = temperature in Kelvins
Q = thermodynamic reaction quotient
F = Faraday's constant
n = number of electrons transferred







Term 3 : Organic Chemistry ( my fav!!!!). Okay, so basically this term only need memorizing works . The chapters included : Introduction to Organic Chemistry , hydrocarbon , haloalkanes , hydroxyl compounds, carbonyl compounds, carboxylic acid & derivatives, amines, amino acids & proteins , and lastly polymers . If u r those who loves memorizing then I’m sure u can master these chapters well, if u r not, then u have to work hard by studying everyday ~( don’t worry, organic chem r like inorganic chem, there’s connection between different compounds, so it’s quite easy to memorize them) . Besides memorizing, u also have to do lots of questions & practices in order to get the hang of it.

eg: reduction of carbonyl compounds ( aldehyde / ketone) to alcohol.






Overall , I like Chemistry the most among the other subjects ( well maybe It’s because I have a wonderful & enthusiastic teacher,Pn Wong who teaches well, she makes chemistry even more  interesting.)Oh , u will also handling a lot of interesting experiments in term 2 and 3 : a lot of colour changing & “ extraordinary ” odours  . Well, that’s all for Chemistry, good luck & all the best in Form 6!

STPM Baharu vs A-Levels

Image
Seeing the A-levels results of the friends around me being released, suddenly I have this urge to write about A-levels and STPM. Many have been asking: Whats the difference between A-levels and STPM? Many comparisons between A-levels and the old system of STPM have been made over the years, but since the implementation of the new STPM system, it seems that there are very very limited (in fact, messy and incomplete) resources around us, hence causing confusions around the SPM leavers and parents. So, my article today will be kinda explaining A-levels and STPM, two of the most popular Pre-U in Malaysia. Before you continue reading, please note that I write this in my view as the first batch under the new STPM Baharu, in the meantime from a perspective of a Pre-U student towards A-levels. Hence, reader, read with an open mind. =) Toughness This, I think will be one of the most often asked question by SPM leavers and parents regarding A-levels and STPM. It is common to li

STPM Results - The Mindset

Image
The time has come for the STPM 2013/14's batch of STPM students to receive their First Semester's results! Here is a short article that might help you mentally on how to prepare yourself for it - and aftermath of receiving your results. #1 Rule: Expect Nothing This is the only way to prepare yourself mentally, because this is your First Semester's results and there are way too much of different circumstances in STPM. Don't give yourself excess stress by setting a target for yourself before receiving your results (if you wanna do so, you should have done it in the start of the semester and go all in for it anyway). Well, just tell yourself that you have did your best and leave it fate to decide. Hence, expect nothing and when the results turns out to be good then take it as a bonus, you'll definitely happier by this way.  #2 Rule: Know That You Have a Second Chance Well, this thought is definitely not advisable during the semester, as I would always

STPM Baharu In Depth - Further Maths

Image
This article is an introduction of the subject Further Mathematics in STPM Baharu by a friend of mine. In Form 6, there are very few people that take up Further Maths and I am really lucky to have a friend who took this subject and is willing to share his experience in this subject. Well, read on! Overall STPM FM is introduced for those who has intense interest in math and wish to challenge themselves in STPM. It can be only be taken with Maths (T). Being a 100% written test, you don’t have to do any assignment or project. Since there are less than 30 candidate taking it each year, there are no any reference book selling in the market and no teacher teaching it in school (as far as I know). You can only learn it by yourself or going for tuition. The reference book recommended by MPM is hardly found in normal bookstore. You may order it from MPM or online but they are really expensive (each book cost about RM 200) and you may need 4 different books for the whole STPM. Most of u
