onSET C-Test: Exam Format and a Strategy for the 160 Gaps

onSET is a C-Test, a shorter German placement test used for admission to certain VWU programs and for scholarships, separate from the full EPD exam. Here is how a gap actually works, the scoring rule, a critical detail about umlauts, and where to spend your time.

How a gap is built

The test is eight short texts with exactly 20 gaps each, 160 in total. The first sentence of every text stays intact to set the topic. From the second word onward, every second word loses its second half: in Menschen, for example, you see Mens and have to write chen yourself. When a word has an odd number of letters, the visible part is always the longer one. The texts carry no fixed level label; the task bank spans roughly A2 to C1, and difficulty visibly increases from text to text.

The umlaut rule

A specific trap for anyone typing on a non-German keyboard: umlauts must be typed as real characters, ä, ö, ü, and substitutions like ae, oe, ue count as wrong. The fix is simple: switch to a German keyboard layout, or use the character row (Auswahlzeile) shown under the text, where ä, ö, ü and ß are one click away.

Scoring and why guessing is free

Every correct gap is worth 1 point; a wrong or blank answer is worth 0, and there is no penalty for a wrong guess. That gives you the single most important rule of strategy: never leave a gap blank. A reasonable guess is never worse than an empty field.

Your time budget: about 15 seconds per gap

Each text gets 5 minutes, after which the next one loads automatically, for 40 minutes total across the test. That works out to roughly 15 seconds per gap on average, but most gaps take 2 to 3 seconds once you read the visible start and the sentence around it. Spend the time you save on easy gaps on the hard ones, not the other way around.

Strategy: read the whole sentence first

Before you fill a gap, read the entire sentence: the clue often sits after the gap, not only before it. Articles like der, die, das, den, des fix the gender, case and number of the noun that follows, so looking to the left of a gap frequently points to the ending more reliably than the visible word start alone.
