Retrieval practice & spacing
Re-reading your notes feels productive and mostly isn't. MedSpire is built on the two things the evidence actually supports: testing yourself, and doing it again just before you forget.
Question 12 · Tubular function
Filtration at the glomerulus is non-specific. What therefore determines whether a substance is excreted in the urine?
Why: because filtration is non-specific, what ends up in the urine depends on how the tubule modifies the filtrate afterwards.
Most revision stops at step one. The last three are where the material stops sliding out of your head.
Each lecture broken into subtopics you can open one at a time, so you're reading a section — not scrolling a wall.
GFR is 125 mL/min, or 180 L/day — the kidneys filter the whole plasma volume about 60 times a day.
Every question tells you why the right answer is right — and asks how sure you were, so a lucky guess doesn't get filed away as knowledge.
How sure were you?
Right, but you weren't sure — this one comes back.
Spaced-repetition drills bring each fact back just before you'd forget it, which is the whole trick to remembering things months later.

Smart review quietly tracks what you keep missing and builds a session out of exactly that, mixed across topics so you're not cramming one thing.
