Guides
The stuff I had to dig through university websites and printer manuals to find out, written down once so you don't have to. Every guide says when it was last checked and links where the facts came from.
Highers and uni
3 guides- 2027 entry · Computing Do you need Higher Maths for Computer Science in Scotland? Which Scottish universities require Higher Maths for Computer Science in 2027 and at what grade, the nine where you can get in without it, and the one that runs a no-Maths degree you can transfer out of.
- 2027 entry · Medicine What Highers do you need for Medicine in Scotland? The Highers, Advanced Highers, National 5s and UCAT each Scottish medical school asks for in 2027, plus the widening access offers and gateway years, all from the universities' own pages.

Filament printing
7 guides- Materials PLA or PETG: which should you print in? The difference between the two most common filaments in plain terms, what the test numbers actually show, which is easier to print, and the build plate mistake that PETG punishes.
- Finishing How to fix elephant foot on 3D prints How to tell which cause of elephant foot you've actually got by measuring the part, the current compensation paths and shipped values in PrusaSlicer 2.9.6 and Bambu Studio 2.8.2, and how to get the lip off a print you've already made.
- Finishing How to remove 3D print supports without leaving marks How to get supports off PLA and PETG cleanly, which tool does which part of the job, how to clean up the surface underneath, and what to change before the next print so there is less to clean up.
- Getting started What tools do you need for 3D printing? What your printer is already bringing, the three tools that actually finish a print, the one in the box to be careful with on your build plate, and what to leave in the basket until you need it.
Filament or resin
3 guides- Finishing How to paint a 3D print so it doesn't peel Why paint won't hide layer lines, what filler primer is actually doing, the recoat timing that makes spray paint wrinkle, and why spraying in a cold Scottish shed fails for most of the year.
- Finishing How to sand a 3D print smooth Which grit to start at and why, the reason PLA has to be sanded wet, what the numbers on sandpaper mean, how to tell when a grit is finished, and where to stop if the part is getting painted.
- Choosing a printer Resin or filament: which 3D printer should you buy? What the two kinds of 3D printer actually do, which one gives finer detail, what each really costs in the UK, and the handling and waste that comes with resin. Written for someone who hasn't bought either yet.
