We are doing a practical exam. Teacher's being a bitch and not telling us what the practical is(bio did). It apparently changes every year. My appeals went without ears. I'm kinda concerned on what can be examined. Module 7 has really difficult practicals. One of the practicals was a zappy...

I'm garbage at Physics. I'm not very good at any subject but esspecially bad at Physics. My raw mark is currently 57 percent. I imagine I'm ranked bottom 4 out of around 23. My friend has a 90 percent raw mark and he's ranked around 8th himself. School did an ass job with the assessments. There...

When studying for one of my exams, I noticed that lots of questions were exactly the same as in other high schools. Some questions were literally written word for word. Such as that "marty the martian socks" perms and combs question.

This question is replacement question 14 2012 hsc from the excel 2022, if anyone wants to see. Question 14(4 marks) (a) The population of a gold mining town is initially 8000 people. This population would increase at a rate of 1.5% per year, except that there is a steady flow of people leaving...

My strongest subject is Maths Advanced and my weakest is Extension 1. My go to method for advanced is trial paper and win. I'm too dumb for Ext trial papers. I never get the harder questions corect. Did 2009 and 2018 Excel HSC. I did yr11 diffential calculus, polynomials, trig, and year 12...

The local maximums nad minimums are swapped. Am I just dumb, or were the sydney grammar teachers dropped on the head as children

Bruh. They went hard and they kept getting harder. I got almost all the answers wrong For comparision, I did 2022 North Sydney Boys, and that was a piece of cake. I only got like 2 questions wrong, and one of the questions was a kind of question that wasn't taught in school. The weird ass one...

Okay. Luckily, the teacher told us EXACTLY what we'll be doing in the practical. What he said: Part 1: We'll be given hydrocloric acid with known concentratoin, and we're to use this to find the concenation of sodium hydroxide. Part 2: We'll use use the derived concentration of the sodium...

All I managed to get out of this is that cos(58) = 12/(5x + y)

I was looking at some vector questions in the pearson textbook and they were a piece of cake. Did some HSC questions that were actually difficult. Why? Also some vector questions would be niceeee.

Kinda stupid question, but I have an exam coming on tuesdah. Sam's book looks very long and complicated, and he occassionally goes off topic, and talks about random shit, such as the trojan horse, or #sddstudents. Notes seem to have all of the actual important information. What is the point...

Latest test. Perms and Combs. I got 49 percent. Teacher gave me a very disappointed look. 3rd lowest in the school. :( Average in school was 64 percent. I did tutoring this term, however my grades didn't increase at all. I did every textbook question i Pearson and Cambridge for perms and...

I looked at the atar scaling for English standard from aligned marks and the difference wasn't that different. Literally a .10 difference most of the time, and assumed that the difference was from alignment. I looked at alignment and discovered that alignment for English standard is not that...

We are supposed to research a chemical reaction, but I honestly got no clue how to create a question that adheres to the specification of the assignment. When I tried to compose a question, all i could come up with were questions like "how is x reaction started" and that is a stupid question...

currently doing extension 1, and it's easier than advanced. Just wondering if doing extension benefits advance? Also how helpful is a tutor for you? I don't see the value in one so I don't have one, but my friends say that having a tutor really helps them
