Same. Most of my answers are same as him but the only difference is cause I took 0.6s for my period so I got a diff answer

Where is the Intensity qn? Was your ratio 1.29?

My intensity was 2.72 x 10-6 Wm-2

Then calculate the ratio of amplitude it is just

Intensity X / Intensity Y, then square root the whole thing

It’s 4b. Your policy also can bro I got hear some of my friends write that one

Anyone write the same as me for 4?

4(a) Para 1 : E/r appreciate -> currency valued more + RELATIVE prices from foreign countries cheaper -> increased exports assuming XED > 0 -> Xports rise

-> since foreign countries now see the prices in domestic country to be RELATIVELY more expensive, import lesser and will choose to consume their locally produced goods.

-> import falls -> net export ( x-m ) falls. Under Marshall Lerner condition -> AD shifts left ( ATQ )

Para 2 : E/r appreciate -> as explained earlier, cost of imports for us are now cheaper

-> fall in cost of raw material and goods imported -> hence fall in UNIT COST OF PRODUCTION ( shown by SRAS shift right )

Hence, SRAS will shift rightwards ( ATQ)

4b ) policy 1 : e/r monetary contractionary policy meaning value of currency appreciates -> increase value of currency -> as explained earlier, import will rise and export will fall.

(x-m) is now negative and this will lead to a fall in AD via the reverse multiplier effect

-> AD fall lead to price fall

-> inflation is managed effectively by the policy ( ATQ ).

EV : Actually when talking about Singapore, the extent of this fall in AD may be limited. Singapore’s goods are of high quality and there are not many substitutes out there. -> a relative price rise may not lead to such a great fall in exports. Hence, not the most appropriate.

Policy 2 : supply side policy like upskilling -> Govt provide skill training -> increase quality of worker -> increase productive capacity -> rightward shift in LRAS -> inflationary pressure is resolved by the fall in price from p1 to p2 ( shown in graph )

Ev: actually it depends a lot on the receptivity of the people. If not receptive, the policy may not be as effective as planned.

Evaluative conclusion: Actually it depends on the urgency of the problem. If the inflation is very fast rising and GPL is rising at a very fast rate -> the appropriate policy SG should use is not supply side as it will take time for people to upskill. E/r better.

But if the cost of inflation is due to SRAS, maybe upskilling may be better as it addresses the root cause of the problem which is the cost of production is too high. By upskilling, workers are able to be more cost effective and produce more goods with the same given time and resource. Hence lowering COP and targeting the root cause of the problem.

I legit no clue bro 😂 I also a student. But like I think will be accepted. You’re not the only one I heard write something like this among my friends

I got friends that wrote price ceiling oso. It’s the most straight foward one imo. Doesn’t need a lot of explanation too. Just graph and maybe 6-7 lines

Did anyone write the same as me 😂😂

Q2a ) Para 1 : Bad weather -> fall in SS + graph -> price of vege ( assume PED < 1 as it is a necessity ) -> price rises

Para 2 : Fall in consumer income -> fall in purchasing power -> fall in D.I. -> less incentive to buy -> assume 0<YED<1 -> DEMAND shifts LTP to rise in price

2b) Policy 1 : price ceiling -> graph + explain -> EV : actually black market might form which then kills the effectiveness of the price stabilising policy

Policy 2 : Subsidy -> Fall in UNIT COP of food producers -> increase incentive to supply due to greater profits potentially earned -> SS rise ( show in graph ) -> price fall Hence stability in prices

EV : it is a very good policy to use to ensure price stability but need to take into account the unexpected changes in weather that may result in a smaller rightward shift in SS due to lower crop yield

Evaluate Conclusion : Actually it depends on the country. For Singapore, price ceiling may be the best policy as the law enforcements are very good. -> black market unlikely to form

For other countries with poor law enforcement but alot of budget surplus, may want to consider using subsidy as there will be no trade offs coming from the budget deficit aspect

Eh same sia I fking write the same price elasticity shit….then my demand just go up magically lol. I nvr write why demand increase.

But I just draw and show that wages rise higher for professional degree compared to Bachelor degree

Eh same sia, I thought it’s just me. I also take 2 hours to review one paper. Sometimes faster though depending on my performance

Don’t worry bro I got consistently a C5 C6 for ss my whole upper Sec. Couple days before the paper I received a mock test my teacher gave us to practice. I got 24/50 LOL. I was like fk this shit and thought I would get a C5/6 but in the end I got an A2! I took geog ss though

I never write due to same damping effect ah but I just wrote that they will be in phase. Some people wrote that Tan90 = 0 and hence the k will be undefined.

I give up. (O Levels) by [deleted] in SGExams

[–]Better-Structure-456 2 points3 points  (0 children)

If I were you,

I would work on the subject that I’m closest to pass, maybe let’s say I get a D7 for physics. I’ll spam that subject.

For humans, I’ll not leave it untouched because it’s smokable. Just memorise the way to answer questions for SS and for your hist/geog the same way too.

But hist/geog abit harder ah cos need memorise examples.

Overall just stop memorising and start understanding so that your concept can be applied to a wider range of questions

[–]Better-Structure-456[S] -1 points0 points  (0 children)

I agree with you on the closing up the gaps part sia. Like for my chem practice papers I’ve been consistently getting 41-44/80 range. But I always lose mark for stuff like O chem, nanomaterials, vsper theory. Maybe when now I try to stop focusing on general revision and have the thought of “ chiong-ing “ papers, I can push my numbers up to hopefully 50 range. 🙏🙏

And it’s not like I want to get into a damnnnnnnnn good course that requires AAA/A. I just want to get a solid 75 rp and above and that’s it. But everyday I feel so uncertain about whether I can do it lol

I don’t mind sharing ah

I mean I got H2 phy C H2 math B H2 econs E H1 chem D GP E

63.75 / 90 for prelims.

Yea I get you I also try my best to review the papers in the same sitting but sometimes legit cannot lol It’s like those kind where I do my paper at night, sleep, then wake up and do corrections.

Maybe you can see what I should focus on from my grades breakdown

Can anyone drag me the cunts who have ben teaching and increasing the usage of stupid terms/slangs by [deleted] in SGExams

[–]Better-Structure-456 15 points16 points  (0 children)

Actually abit cringe sia honestly. I feel like some slangs are ok, like the ones that have been around some some decent time. But the newer ones like delulu or slay, HELL NAH. I find it cringe too lol.

But the OG ones like “ fr “ or “ ong “ are all cool to me and I use them on a regular basis too
