Hi everyone,: ),I am new here!!!!! Can somebody add me in the list of SPM 2013 candidates,btw I am a pure science student,9 subjects

I reckon you to focus on all the vital points(isi) in each subtopic that you have learnt by doing short notes,especially the ones that are gonna come out in the essay questions. After you have memorized all the points, then you should try out some exercise to refresh the information that you've stored in your brain. Btw,its a really good idea to refer to textbook than rely on your revision book,and doing SHORT NOTES really does help you if you're coerced to doing last minutes revision,GUD LUCK!!!!

As you can clearly see,the arrangement of the bulbs A,B and bulb C is in parallel form. This is due to the fact that the current that flows from the anode has two pathways to reach the cathode: --->the 1st pathway is through bulb A ---> the 2nd pathway is through bulb B and C,which is connected in series. And as you can see,bulb D is arranged in series form that has been separated from the others bulbs,so bulb D will light up the brightest. Let me briefly explain as to why bulb D in series form is the brightest:

side notes: I=current

Let's say
bulb A=Ia
bulb B=Ib
bulb C=Ic
bulb D=Id
As I said earlier, bulb A,B and C is branched in parallel form,but bulb B and C is arranged in series form. So,the total current flows in parallel is: I(total)=[Ib=Ic]+Ia
Hence,the current supplied by the battery is as same as [Ib=Ic]+Ia
Since bulb D is in series,its current will be as same as the total current supplied by the battery,which also means that:
I(total current supplied by battery) = [Ib=Ic]+Ia = Id
As you can see,you can roughly estimate that the value of Id is much larger than Ia,Ib or Ic. And since the brightness of the bulb depends on the current,it can be concluded that bulb D glows the brightest,since its current is the highest among all of the bulbs.
I had done several questions that were as same as this,so I am quite sure that my theory is correct,if it is wrong,then kindly correct me. Hope you fathom the explanation.

It seems like Numerical Methods is quite interesting,btw I wonder if its tougher than Calculus or on par with it

Yes,you're correct Gratz the ans is 110/14/15 π units2

You've did a very astute observation and btw, I concur with the fact that we should indulge in the questions and try to fathom and solve it before anybody else solve it for us, for it can ameliorate our mettle and at the same time improve our critical thinking skills

Well, I certainly distaste my performance in this mid-year exam. I did lots of awful flaws and I even made several silly mistakes where I shouldn't Nevertheless, I'm gonna try to do lots of revision in this upcoming holidays, especially for my BM and BI (I'm really weak in these 2 subjects). Btw, trying to remind myself everyday that SPM is really nigh

Well, I reckon you to revise on essay (karangan fakta), which is the 'Belly of The Beast' for BM, if not most. You see, if you could wisely find several points (isi-isi penting) or perhaps surf online and ask Mr.Google regarding the tips on how to write pendahuluan, isi or kesimpulan regarding any essay that you favour, you could simply master it without any coercion. For example, you can try to get as many points as you like regarding karangan that sounds like these : 'kesan-kesan penyalahgunaan dadah' , ' kesan-kesan pencemaran alam sekitar' and etc. If you're able to relate the subjects(person/people) into the karangan, for example: pihak ibu bapa patut... pihak kerajaan hendaklah... golongan masyarakat seharusnya... instead of just focusing on one point/person and superfluously elaborate it, then your karangan will get more flawless

Wow! Looks like you're back and really pumped up,maximR, good for you As for me, I totally flop in this mid-terms in the aspects of BM/BI and not to mention Biology, if you must know. Btw, its really good to see somebody like you try to muster up your spirit and get back into the track instead of looking back and feel regret or give up. You really motivated me,dude

*Sigh* Finally,can't wait to relish this mid-year semester's holiday after a long and tiring battle,darn,all of the last-minutes revision did wore me out. Gotta make sure I never pull the same trick ever again in this upcoming SPM Trial or else I can just kiss my dreams of getting straight A+ goodbye

Damn It seems like only I haven't received any news or anything about the Kerja Kursus Matematik Tambahan,yet. I would really like to settle it this holiday if my teacher gave me the project, but it seems like I gotta occupy my holidays vacancy on other things though.

I guess you've made a little error there fellas, every student is obliged to complete the Add Math folio whether they like it or not, it's just depends on when do they have to do it, that's all there is to it.

Well, I reckon your teacher keeps it as a secret out of personal reasons or, maybe because you guys haven't even question him/her anything regarding the Add Math folio, so he/she just keeps quiet about it, but sooner or later you will have to do it. Btw, I had no idea that your seniors haven't even got a clue about the Add Math folio. Anyways,FYI, the Add Math folio that we're dealing with in this year kinda resembles with our Kerja Kursus Sejarah Tingkatan 3.

I'm concur with you I still remember that I spent for about 20 minutes solving a rather confusing and mind-bending question that involves basic identities, but when I look up on the Internet and found an exactly similar question with the ones that I faced, I realized that, its not that confusing or extremely hard, but its rather very tricky,and all it needs is 5 to 6 simple steps to solve it I reckoned that basic identities is more of a puzzle-solving question rather than a pure mathematical question.

Btw Edunation Malaysia also provide numerous tutoring videos that are quiet helpful too Unlike Msia Free Education which focus solely on maths and Add Maths(though the tutoring videos are really helpful), Edunation Malaysia covers variety of subjects that range from the pure science subjects(Physic,Biology,Chemistry) to accounting subjects

Finally, I'm back from my long hiatus of vacation during the first week of holidays. In other words, I still have about less than 1 week left before I'm back to school. Seems like time really flies away faster this time. Anyway, can anybody help me solve this question that I faced,by the way its SPM chemistry chapter 4(Thermochemistry)

This post has been edited by RED-HAIR-SHANKS: Jun 3 2013, 05:25 PM

Oohh, I get it now ,thanks for your guide. By the way,this is how I solve it,hope its correct :
1 mol of water = 54.6kJ of heat released
so, 0.5 mol of water=27.3kJ of heat released

According to the thermochemical equation, 1 mol of KOH reacts with 1 mol of ethanoic acid to form 1 mol of water.
So, 0.5 mol of water is formed by the neutralization of 0.5 mol of KOH with 0.5 mol of ethanoic acid.
number of mol of KOH=MV
0.5 mol =(2)V
V=0.25 x 1000
=250cm3

Yeah,finally complete chapter 4 thermochemistry,looks like I only got 1 chapter left before I can complete the entire syllabus of Form 5 Chemistry. I really hope to finish the whole thing by the end of this weekends, though I lack in doing exercises and questions regarding the Form 5 Chemistry,which will do nothing good to me even if I'm able to finish the whole syllabus. And not to mention that I studied really really slow,which irritates me Currently I'm entering chapter 5 (Chemicals for Consumers) in the topic of preparation of sodium alkyl sulphate and sodium alkylbenzene sulphonate(it really gives me a big headache just to fathom its formation of long-chain hydrocarbon),by the way I just wanna know how're you guys progress during this holidays? Anyways, make sure you guys have fun and relish this holidays,though

Looks like we're in the same boat fella
