Is it better to sleep while missing a couple questions from a review package now instead of spending 40 minutes doing all of them at midnight?

Hi, am a grade 12 student and I plan to do engineering after high school. To anyone who is an expert at studying for their tests either a couple or a few days before the test day, is it better to just skip the 6 questions you need to do for review and go to sleep when its past your bed time? Like if I am supposed to sleep at 11:30 but its 12:45 now since I have been studying half of the day, should I just go to sleep now and save the problems for tomorrow morning while getting a goodnight's sleep?

I need this type of advice especially for classes like chemistry, physics, and math.

How can I answer projectile motion problems in physics?

I am taking physics 11 university preperation physics class, and I am struggling with understanding on how to approach and solve projectile motion problems. Now fortunautly, this is the last thing we are learning in kinematics. From what I know about this, the acceleration is always a = -9.8m/s2, and I have to create 2 equations for horizontal and vertical sides. I do always draw a diagram to help me visualize this, but I still am struggling to how to approach it.

In these problems, do I have to at least make 2 equations to get the answer I need?

How is calcium less than argon in this chemistry question?

Hi, am a beginner in chemistry, and we are learning about periodic trends. Now this question got me stuck for a bit and made me draw out the electron shells and how many electrons each element would have, and how much electrons would be left if they are an ion.

Now I thought the answer would be that they all have the same radius’s since all of them had the same electrons with 2 changes. Now it said it’s because whichever element has the most protons but equal as much electrons as the other, it’s less than the next element. Like Ca in this question had 20 protons and 18 electrons, Potassium had 19 protons and 18 elevators, where Argon had both 18 protons and electrons.

Why is b) the answer?

How can I survive a brutal semester that has 3 of the hardest courses in high school?

Hi, am a grade 12 student and I plan to do engineering in university. So to give you a quick summary of what am taking and what I took for grade 12, I already have done 4U english and advanced functions and got an amazing mark for both. Now here is the biggest mistake I made in high school: I didn't take chemistry or physics in grade 11, in which I unfortuantly need to take them in semester 1 in which I am doing right now.

Ok so far it is going good because I am consistently doing my homework, listening carefully in class, and trying to understand more than memorize, especially in physics. Now here is the worst part about my grade 12 schedule, specfically next semester: I have physics, chemistry, and e-learning calculus and vectors (to at least balance everything out and have time to study for a test before), and a spare.

To anyone who took these courses, what tips would you give me so I do really well in all of these courses, especially for SPH4U AND SCH4U? I need to know so that I am ready to tackle on a brutal semester (my final semester) and get into either Carleton or Uottawa university.

How can I find the average acceleration when its giving me 2 velocities at different directions?

Hi, am a beginner in physics, and I am doing kinematics, grade 11 physics right now. Now if a question asks you to find the average acceleration for 2 velocities that are in different directions (along with the time), are you supposed to add or subtract the final - initial velocity?

The textbook question am working on is this: A squash ball with an initial velocity of 25 m/s [W] is hit by a squash racket, changing its velocity to 29 m/s [E] in 0.25 sec. What is the squash ball's average acceleration?

Now I know their is 2 answers to this, but the answer on the textbook says its 2.2 x 10 squared m/s2 [E], but when I added both of them instead, I got 216. I assume they just rounded the 1 to a 6 and made it 2.2?

I also subracted, in which it gave me for my final answer as 16.

How can I stop distracting myself with listening and blasting music in my ears and walking/dancing around my house?

Hi, am a 17 year old teenager. For years, I have had a strong addiction to music, that I get hyped up a lot nearly everyday and I start roaming and dancing around my house, blasting music in my headphones, while the tasks and chores I need to get done are constantly stuck in my head and I keep delaying them, sometimes even possibly for hours. Anyone who is a productivity expert, what tips can you give me so I can permanently break this addiction and become great at managing my time and having consistent discpline within myself? I have tried putting my headphones in a seperate room, but that still didn't work. Should I sell these headphones and just use my airpods? Yes I have airpods and a headset. I only brought a headset because my airpods drain their battery fast, but those headsets were cheap and their battery percentages last for days before I need to charge them again.

I am going to become an adult soon and head to university, so I need to find an effective way to break this addiction and become well prepared when I become an adult, and for my final school year (this year), especially that univeristy is going to be more stressful

__H2SO4 + __B(OH)3 -- __B2(SO4)3 + __H2O. In this chemical balancing equation, why is their supposed to be a 6 in the H2O?

Hi, am a beginner in chemistry, and I need help with balancing chemical equations. They are my weakness currently, and this question got me stuck for a while trying to figure out, on why would the H2O have a 6 to it if in the (SO4)3 already has 4 sulfurs and 12 oxygens. How can I avoid this trick next time? Because the answer key had 3 and 2 on the reactants side, but on the products side is what got me confused when they put a 6, instead of a 3 (thats what I put as my answer at first).

Why do many elements in the periodic table, have the same amount of electrons as the amount of protons/atomic number they have?

Hi, am a beginner in chemistry, and this is grade 11 chemistry. I am struggling to understand on how many electrons each elements have, because on my worksheet, the electrons have the same number as the protons and atomic number of that element. I need an explanation

So here is what I did and I got it wrong because thats what I thought I needed to do to find the electrons for that element. Magnesium: it has a atomic number and protons of 12, but since it has a 2+ charge to it since it is losing 2 charges, I did 12-2 and got 10, I thought that was the answer, but it turned out that the electrons are just 12 as well.

How do I prepare well for physics, and physics 11, university preperation?

Hi, am a beginner to physics, and am just taking physics 11 university preperation. Why do so many students struggle every year in physics, and what can I do to be successful and the top student in my class? Well to be more specfically, lots of students decided not to take physics in-person, and rather did it online to escape from the tests and quizzes, but am confused on why physics is considered one of the hardest courses in high school.

What do I need to know on how to do well in chemistry and chemistry 11, university preperation?

Hi, am a beginner in chemistry and I have just taken chemistry 11, university preperation. To any chemistry experts, what tips can you give me to be successful in chemistry and be the top student in my class? I am already consistently doing nearly all of my homework (I skip the ones that feel repetetive), and I challenege myself to do the hardest questions without any help. The reason am asking is because so much students are apparently struggling with chemistry every year, and I need to know what is this issue on why chemistry is considered very hard. A classmate from my other class said she would have been depressed if she decided to take chemistry 12 after taking chemistry 11.

What does it mean when your calculating the weighted average of the percentage abundance of a question? And why is it important?

This is chemistry 11, university preparation. So right now me and my class are studying about isotopes, finding the average atomic mass and percentage abundance for a certain isotope in a word problem. Now my question is, when you need to find the percentage abundance of another isotope or 2, and your already given the percentage amount for the 2nd or 3rd isotope, like 30.64%, why do we need to subtract it by a 100, then divide it by a 100, to make our equation this: x = 0.6936 - y?

Note: Am a beginner in chemistry so I need to understand rather than memorize most of the time

Is mechanical engineering considered better than accounting in 2026 and beyond, especially in the AI era?

Hello. I am a grade 12 student and my school is starting in a month. To give some information about my interests and what I wanted to pursue in university, I wanted to do computer science, but my brother is a data scientist and warned me that computer science and a majority of these tech jobs have a lot of competition. He also warned me that AI is now writing code for a lot of companies, where employers are likely to be paying their employees less, but AI will not replace the job though completely. At the very first, I did bad at grade 10 science, got a 60% final primarily because biology screwed up my mark badly, but I did do ok in chemistry and physics. My family keeps telling me to pursue accounting and just stick with it since that’s what I told them first, but then my interests changed a lot and I now want to become an ME since computer science is not good this time. I did wanted to pursue accounting but I realized that some work is already being automated by AI, but my older siblings tell me that it’s easier to find a job and that engineering students often struggle to find job after graduation, even with a mechanical engineering degree. Now I deeply regret not taking chemistry and physics in grade 11, but I did already take advanced functions grade 12, as well as Grade 12 English. I can just take grade 11 chemistry and physics in first semester, with a free grade 12 course like drama, and a spare. Then in semester 2, I already am doing calculus and vectors e-learning or online, then I can take grade 12 chemistry and physics in semester 2. I genuinely have a much better passion for mechanical engineering rather than accounting, but at the same time I am not saying that accounting is terrible or bad. It slightly fits in my interests, and I’ll be honest, I primarily told my family and teachers that I wanted to pursue accounting, but I was doing it for the money, stability, not a very hard degree, and it’s one of the fewest jobs you can get with just taking the 2 math courses and grade 12 English. Now for the mechanical engineering students and workers, what would be my best plan to do right now before school starts? My family doesn’t inherently force me to take something else, but they strongly warn me about it, but I primarily trust research more rather than purely trusting everything my family says to me. If I confirm that I will study mechanical engineering, I can use semester 1 to significantly build up my chemistry and physics skills, that the majority of the formulas and concepts I learned will remain in my head when it’s semester 2, especially when semester 2 is intense, though I will have a spare.

As a beginner to learning about Java, how much time should I spend each day learning about programming and Java when I am a complete beginner.

Ok so I am entering grade 12, and I need to learn more about programming and Java since am taking the grade 12 computer science course this school year. I plan to pursue computer science in a Canadian university but I need some guidance from professional programmers on what is the best way to learn more about programming, especially Java the programming language. Ideally, is it recommended to learn/code on Java 1-2 hours a day? I need to learn Java since in my school, grade 12 computer science will teach and test you about Java, since in grade 11 they taught and tested me about python.

Is a computer science degree still worth taking at university in 2026, especially how advanced AI is now?

So I needed to create this post because I have a strong passion to creating software using computers, creating apps/programs for the digital world, etc. It is my dream to build software and create apps in technology. However, I got told multiple times that these technology degrees are not worth it anymore because of how AI is advancing so fast, employers don't even need workers or junior roles anymore. I AM SEVERELY WORRIED to how AI could take over these programming/tech jobs or even just pay there workers a low-mid wage income since AI would do most of the tasks. So from any professional programmer or computer scientist that has a lot of experince in these tech jobs and hirings, should I continue pursueing a computer science degree in university (and would it pay a high salary like ($100k-250k), or should I just study something else like accounting or engineering? For you guys to be aware, my family is basically clowning on me for pursueing a degree that "AI will replace it and it will write all of the code for apps", and I am just terrified if this is how the global workforce will work from now and in the future, like we will have AI doctors or therapists treating patients and kids. I don't mean to take up so much of your time, but I am entering grade 12 and I need more information about CS, and yes I absouletely have the work ethic to work a lot on math and different programming languages.
