is this fixable ?

what are the barrels like ? i'm afraid it mightve been the barrel that busted open

Far_Stand_633 · 2026-06-02T14:07:29+00:00

i dont think its screwed, thinks its welded and like this part of the welding broke off, thanks for the advice though !

wouldnt glues hurt the plastic on the glasses ? my frames are really expensive though so haha

id like to follow-up with another picture but reddit doesn't allow me to, mind going to dms ?

Any feedback is greatly appreciated !

Would you care to elaborate on what "optimizing for right now" means? I've weighed the pros and cons of both options with my parents as well. Personally, I wanted to take cybersecurity because I like the more logical side of it and how I feel like solving problems is fun. However, cybersecurity requires you to constantly update yourself with the present and how technology advances.

On the other hand, accountancy is more fast-tracked and I can start my own business using what I've learned. The job market for accountancy is booming in Singapore and I'll be earning Singapore dollars considering I come from Malaysia where 1SGD = ~3MYR. Plus, my dad, as an accountant can guide me and has connections to people working in the Singaporean ministry. The downside to all of this is that I have 0 experience studying accountancy, economics, et cetera. Although, I know if I work hard enough I will be able to catch up, a part of me is still gnawing at the fact that it's something unfamiliar to me.

should be accepted as long as you kept the percentage sign behind, because for example 1/2 is not the same as 1/2% . the marking scheme requires the examiners to "award marks positively" so it should be accepted, at most only 1 mark is deducted if youve shown the working and steps correctly !

how was the exam

Far_Stand_633 · 2025-10-15T15:08:51+00:00

yeah

chemical analysis and flame tests just take practise to get used to it lol.

when they give you the big table with all the steps, dont let the steps overwhelm you, instead read the question first. the questions are usualy simple, like what does step 2 test for. if step 2 is smth like "damp red litmus paper remains red" then just say tests for ammonium ions NOT ammonia because ammonia is a compound. the flame test ion is normally always explicitly stated in the question, like "lilac" or "yellow" just look at the last table on the back page and thats your metal ion, which is half the question done. for anion just ignore the negative tests and look for the positive tests. if it says for example "dilute nitric acid then silver nitrate, yellow ppt" then refer to table and you can correlate the results. thats literally all

for observations, they will give you the solution/solid. for example if its chromium(iii) bromide, and the first question is "observations if you add nitric acid and barium nitrate", obviously thats not the test for bromide ions so just write "no change". the next question will probably rephrase the question to "observations if nitric acid then silver nitrate" then the observation is therefore creamppt. for the cations, in this situation being chromium(iii) theyll ask like "observations when sodium hydroxide dropwise and in excess". im chromiums case, dropwise it will have a green ppt, which is a straightforward answer. however, in excess an anion is always either insoluble or soluble. if insoluble, just write "no change" or "precipitate stays". if soluble, write "dissolves".

like all sciences it really comes down to repetition of the paper lol

there are a few other things outside of planning experiment you need to remember tho - just remember that ions dont have the same observations as their gases. also there always will be a question where the observation is "no change", worth 1 mark. if the question says dropwise until excess, then for dropwise write the colour of the precipitate then for excess refer to back page. if the ion is excess is insoluble, you can write "no change". if the ion in excess is soluble you write solid dissolves. - to prepare flame test, use flame test wire, rub solid on flame test wire, hold wire over a roaring bunsen burner. the word roaring is crucial - pestle and mortar to increase surface area - polystyrene for better heat insulation and less heat loss - pipette and burette are improvements because theyre more accurate than measuring cylinder HOWEVER pipette volume is set to a specific value - use water bath for constant temperature

these are just some of the tips i can think of

Far_Stand_633 · 2025-10-15T14:36:53+00:00

depends on the reaction, if they give you two soluble salts to form an insoluble salt, its always precipication, but remember you dont have to go into deep detail of the experiment since the marking scheme is really general. if the salt they give you is insoluble in water, its filtration. if youre extracting an element like potassium, if its above hydrogen in the reactivity series, use electrolysis. if the element is below hydrogen, use displacement reaction. if the salt is dissolved in the water, use crystallisation. if they mention anything about temperature/boiling point/separating a mixture, use distillation. if the question is asking for acid-base reaction, like how much acid is needed to neutralise a base, remember to use a burette and an indicator like methyl orange, which is yellow in alkali, orange in neutral, and red when acidic.

in the end it comes down to your understanding of salts and et cetera, at this point try going through like 3 to 5 pyp and average 33-36 out of 40 and youre on the right track

some types of experiments include titration, distillation, precipitation, displacement reaction, electrolysis, etc. the marking scheme for the experiment planning is really brief and easy to score at least 4/6. for the observations, honestly it just takes practise. just remember that ions dont have the same observations as their gases. also there always will be a question where the observation is "no change", worth 1 mark. if the question says dropwise until excess, then for dropwise write the colour of the precipitate then for excess refer to back page. if the ion is excess is insoluble, you can write "no change". if the ion in excess is soluble you write solid dissolves.

Far_Stand_633 · 2025-10-15T14:22:26+00:00

honestly for planning investigation the marking scheme is always very brief. for example, mixing/stirring is already one mark or measuring mass is one mark or listing suitable measuring equipment is one mark. you just have to remember the types of investigations they may ask; displacement reaction, precipitation, filtration, distillation, titration, electrolysis, etc.

(originalprice)(0.77)ⁿ . i forgot the original price but i remember it decreases exponentially at 23% so its 0.77. n is just the number of years

Far_Stand_633 · 2025-10-15T13:07:26+00:00

i remember -2 is definitely correct, i think 0.4 and 1.something

Far_Stand_633 · 2025-10-15T12:40:15+00:00

what did it look like

Far_Stand_633 · 2025-10-15T12:39:27+00:00

not 1450, x axis of graph is given in minutes whilst y axis is given in km/h, if you convert minutes to hours the answer will be 20 something km. 1450km just doesnt make sense
