Why the same subjects can score differently depending on how you studied them

Two students came to see me in the same week last October.

Same grades.

Same subjects.

Different outcomes.

One was Priya, who'd been homeschooled in Valencia by her mother, a former teacher from Manchester.

The other was Tom, at a private British school forty minutes up the coast.

On paper they looked like twins.

Both had A Levels in Maths, Chemistry and Biology.

Both wanted Medicine.

But when the numbers came back from the UNED, Priya's file and Tom's file did not match.

Not even close.

And neither of them saw it coming.

Here's the thing nobody tells you.

The Spanish system does not just look at what you studied.

It looks at how you studied it.

The qualification itself matters. But so does the route you took to get it — whether it was a recognised institution, an examination board, a distance programme, a homeschool arrangement your parents registered somewhere.

Two students can hold the same certificate and have that certificate treated completely differently.

Why?

Because the system asks a question before it asks about your marks: is this qualification recognised, and how was it delivered?

That question decides a lot.

It can decide whether a subject counts for the bonus points that lift your final score.

It can decide whether your grade converts cleanly or gets discounted.

It can decide whether you're allowed to apply at all.

Priya's marks were excellent. But the way her education had been structured meant certain subjects were not recognised the way she assumed they'd be.

Tom's route was the standard one. His subjects slotted in.

Same effort. Same ability.

One conversion clean, the other full of holes.

I want to be fair here, because I've met a lot of homeschooling families and most of them are doing something remarkable.

Priya's mother taught three subjects to exam standard from a kitchen table.

Ole for that.

But the Spanish system was never built with that route in mind.

And it does not bend for good intentions.

It bends for paperwork and recognised bodies.

The problem is that most families only discover this at the end.

After the grades are in.

After the certificates are printed.

When there's nothing left to change.

I've watched parents realise, in my office, that a decision they made when their child was fourteen — a choice of programme, a way of registering, a board they'd never heard of — had quietly shaped what universities their child could reach at eighteen.

They didn't make a bad decision.

They made an uninformed one.

And the two feel identical until the outcome tells you otherwise.

Priya got into Medicine in the end.

In her second year of trying.

Tom got in the first time, with worse marks in one subject and a cleaner route in all of them.

That's the part that stays with me.

It wasn't that one worked harder.

It's that the road they walked was scored before they ever arrived.
