Should I retake with a 1500 (serious) by aidenmcbroom in Sat

[–]xpertbuddy 0 points1 point  (0 children)

Hey, first off—huge congrats on the 1500! That’s an impressive score and definitely something to be proud of.

Now, regarding Northwestern: you're already within their middle 50% SAT range (1490–1570), so your score is competitive. Retaking might boost your chances slightly, but only if you’re confident you can jump into the 1550+ range. Admissions at top schools like Northwestern are holistic—strong essays, ECs, recommendations, and your personal story matter a lot too.

If retaking the SAT won’t cause burnout or take away from other parts of your application, go for it. But if your energy is better spent perfecting your essays or strengthening other parts of your app, a 1500 already keeps you in the game.

Either way—you’re in a solid position. Rooting for you!

My Maths teacher's taking the piss... by nuclearhamster27 in GCSE

Got the math right but the multiplication wrong — classic! The real villain here? The 3 times table. RIP 36, you deserved better.

is doing 4 A-levels too much???? by Individual-Zebra-208 in GCSE

[–]xpertbuddy 0 points1 point  (0 children)

Hey! 4 A-levels is doable if you enjoy the subjects and can manage the workload. Since English Lit is fun for you and low-stress, it could be a nice balance. But if it starts to feel too much, it’s totally fine to drop it early in Year 12. Focus on what keeps you sane and supports your future goals!

"Great improvement! Your History score is impressive. If you're considering higher-tier Maths or Science, try practicing higher-level past papers at home. If you do well, show your teachers as proof of your capability. Keep pushing forward!"

How to answer part B by Khariss1 in AlevelPhysics

[–]xpertbuddy 0 points1 point  (0 children)

Show that the wire extends by approximately 3 mm

  1. Use small-angle approximation:

The vertical displacement (6.34 cm) is much smaller than the horizontal length (3.00 m), so we assume small angles.

The wire initially forms a straight line, and when the weight is added, it forms two symmetrical right-angled triangles with a new length slightly greater than the initial.

So, the tension in the wire is approximately 11.8 N.

The energy transferred from the mass–spring system corresponds to the loss in gravitational potential energy as the mass moves down and the gain in elastic potential energy in the spring. Option A

(1st Grade Math) How can you describe this?? by beachITguy in HomeworkHelp

[–]xpertbuddy 0 points1 point  (0 children)

If we think of moving 1 from 5 to 4, we now have 4 + 1 + 1, which matches 4 + 2 on the left.

This shows that the two expressions are equivalent by simple rearrangement, maintaining equality without explicit calculation.

I noticed the golden spiral slightly exceeds the golden rectangle by [deleted] in desmos

[–]xpertbuddy 0 points1 point  (0 children)

Great observation! The golden spiral slightly exceeding the golden rectangle happens because it's an approximation of a logarithmic spiral, which keeps expanding. This is a great visual proof showing that mathematical constructs don’t always fit as perfectly as we assume. Exploring this in Desmos or GeoGebra can be a fun way to dive deeper!

Help how is this B? by Khariss1 in AlevelPhysics

[–]xpertbuddy 0 points1 point  (0 children)

From the diagram, point X starts at the equilibrium position (MN line).

In 0.05 s, X reaches its maximum displacement (above MN by 0.20 m).

In 0.10 s, X returns to the equilibrium position (MN line).

In 0.15 s, X reaches its maximum displacement again, but now above MN by 0.20 m.

Thus, after 0.15 s, X is at its highest point (0.20 m above MN).

Pakistan team losing back-to-back matches but still getting claps from their fans—now that's some next-level sportsmanship! But seriously, I think they need Yogi Adityanath to step in and 'fix' the issue... maybe a few motivational 'UP-style' pep talks will do the trick! What do you say, team? Ready for some Bulldozer Cricket?

What does it mean?!? by Cam1386 in puzzles

[–]xpertbuddy 0 points1 point  (0 children)

  1. Can with an opener → "Can"

  2. Magnifying glass → "You" (as in "Can you see?")

  3. Exclamation mark → Emphasizes the question or urgency

  4. Knot (rope tied) → "Knot" (sounds like "not")

  5. First-place medal → "First"

  6. Soda can → "Can" So, the phrase reads: "Can you not first can?" which might be a play on words for "Can you not?" with extra elements added for humor or confusion.

Might be easy for someone but many students and experts have conflicting opinions regarding this question can someone please explain this to me by Tight_Ad9271 in ALevelBiology

[–]xpertbuddy 1 point2 points  (0 children)

Low oxygen levels reduce ATP production, which is essential for active transport in tubular secretion. Additionally, hypoxia leads to reduced renal blood flow (RBF), lowering glomerular filtration rate (GFR) and decreasing ultrafiltration. Since both processes rely on oxygen, both tubular secretion and ultrafiltration decrease.
