Read and Select

The first question type on the test, and the strangest. A single word appears; you have five seconds to decide whether it is real English. Then the next one. Fifteen to eighteen times in a row.

The Facts


Time	5 seconds per word
Preparation time	None
How many per test	15-18 words, one set
Subscore	Reading
Adaptive	Yes
Scored as	Right or wrong

What You See

One word, centred on the screen, with a Yes and a No button under it and a five-second timer. Click either button and the next word appears immediately. Do nothing for five seconds and the item is marked wrong.

The words come in a mixed set: roughly half are genuine English, half are invented. The set arrives near the start of the adaptive stage, which means it is also the first read the engine takes on your level.

There is no back button, no review screen and no way to change an answer. Every decision is final the moment you click.

How the Invented Words Are Built

The fake words are not random letters. They are built by rules that make them feel familiar, and recognising the rules is most of the skill.

Trick	Example	Why it works
Wrong suffix on a real stem	ambitionate, unhappiment	Both parts are real English. Only the combination is impossible, and that takes a moment to notice.
Real word, one letter wrong	beleive, favoritte, substancial	You recognise the word before you notice the spelling, and the timer runs out while you check.
Plausible nonsense stem	plindow, framble, sprandle	The letter patterns are ordinary English, so the word "sounds like" something you might have met.
Real word from another language	informacion, reponse	Cognates feel right to speakers of Romance languages in particular.

The single-letter misspellings are where most points are lost, because the word genuinely is one you know. Reading the letters, not the shape, is the fix.

Worked Example

Decide in five seconds each

harvest — Yes. Ordinary noun and verb.
plindow — No. Looks like window crossed with plinth; neither makes it a word.
curriculum — Yes.
unhappiment — No. -ment attaches to verbs, not to adjectives. The real noun is unhappiness.
muffle — Yes.
beleive — No. The real word is believe; this is the classic misspelling trap.
shoal — Yes. A group of fish. Unusual, but real, and this is exactly the item that punishes a "if I do not know it, say No" policy taken too literally.

Strategy

Decide your policy before the set starts. Five seconds is not enough to deliberate. If you have genuinely never seen the string, answer No.
Read the letters, not the shape. The one-letter-wrong traps are invisible to shape recognition.
Say the word silently. Invented stems very often sound wrong the moment you subvocalise them.
Check that the ending fits the stem. -ment and -ate go on verbs, -ness and -ity on adjectives. Most fakes break exactly this rule.
Never let the timer expire. An unanswered item is a wrong item. A guess is worth strictly more.

Accuracy without speed does not exist here. If you are still thinking at four seconds, click and move on — the points you save on the next word are worth more than the one you are agonising over.

Common Mistakes

Saying Yes because the word "feels English". That feeling is precisely what the item is built to trigger.
Saying No to every unfamiliar word without exception, which costs you real but uncommon vocabulary like shoal or fungi.
Slowing down after a word you are unsure of. The uncertainty carries into the next three items and costs more than the original doubt.
Treating the set as a warm-up. It is early, adaptive, and it steers the difficulty of everything after it.

How to Practise

Work through 18-word sets at real speed daily. Speed is the skill being trained, not vocabulary alone.
Keep a list of every real word you rejected. That list is the gap between your vocabulary and the test’s.
Study affixes deliberately: which suffixes attach to which parts of speech. This single topic accounts for most of the fakes.
Read widely rather than deeply. Range beats depth for this item.
