NBME 26 Score Calculator and the Wrong-Answer Penalty

Form 26 is a 200-item paper, and the NBME 26 score calculator applies one straight line: 277.22 minus 1.138 points for each wrong answer.

Nothing else feeds in. The NBME 26 score calculator cannot see which systems you missed, how long you took, or the block order.

That slope is second-steepest of the seven Step 1 forms, so the NBME 26 score calculator reads low at a matched count.

Percent correct is the same input: on a 200-question paper the NBME 26 score calculator reads one percentage point as two questions.

Two questions are worth about 2.28 scaled points, so ten questions move the NBME 26 score calculator by roughly eleven.

The pass probability beside the estimate is a separate logistic curve centred on 196, sitting next to the NBME 26 score calculator rather than inside its line.

Near the standard it moves fast. The NBME 26 score calculator pairs 203 with 78 per cent, 198 with 63 per cent and 192 with 33 per cent.

No score report is needed. To run the NBME 26 score calculator by hand, multiply wrong answers by 1.138 and subtract from 277.22.

Offline that gives 232 at 40 wrong, 220 at 50 and 211 at 58, figures the NBME 26 score calculator reproduces exactly.

The CBSSA forms publish no conversion table, so the NBME 26 score calculator is a reconstruction rather than an official lookup. See the modelling notes.

Every row here comes from the engine behind the NBME 26 score calculator, so the chart and the tool cannot disagree.

Zero wrong is 277, and the NBME 26 score calculator then reads 266, 254, 243, 232, 220, 209 and 198 at each further ten wrong.

Below the line it keeps falling: the NBME 26 score calculator gives 186 at 80 wrong, 175 at 90 and 163 at 100.

As percentages, the NBME 26 score calculator puts 90 per cent correct at 254, 80 per cent at 232 and 70 per cent at 209.

The reference table above prints the same NBME 26 conversion chart in five-question steps, and the NBME 26 score calculator supplies each pass probability.

Look at 70 and 71 wrong: the NBME 26 score calculator returns 198, then 196. Rounding on a 1.138 slope steps over 197.

Its bands come off the same line: the NBME 26 score calculator reaches 250 at 24 wrong, 230 at 41, 215 at 55 and 196 at 71.

Raw counts do not travel. Give 60 wrong to the NBME 26 score calculator and it says 209, where Form 28 says 211 and Form 31 says 206.

The NBME 26 score calculator fits a line to one number, and that number is the whole of its information.

Timed in one block or spread over two evenings, the NBME 26 score calculator returns identical digits for an identical count.

Our source table for Form 26 quotes no confidence interval, so the NBME 26 score calculator draws no band around its estimate.

A steep slope makes a miscount expensive: five questions either way move the NBME 26 score calculator six points, against five on Form 28.

Read the result as a neighbourhood several points wide. The last point out of the NBME 26 score calculator is rounding, not measurement.

It knows nothing about the content sample drawn, so the NBME 26 score calculator converts a lucky draw and an unlucky one identically.

A nine-hour exam day tests stamina that a 200-item paper does not, and the NBME 26 score calculator cannot price that in.

A trend across two or three comparable sittings carries more signal than any single reading from the NBME 26 score calculator.

Precision is not accuracy. The NBME 26 score calculator converts an untimed, split sitting into just as confident a three-digit figure.

Form 26 works best as a second or third assessment, when the NBME 26 score calculator finally has something to compare against.

It pairs well with the form before this one, whose intercept sits 0.18 points from the one inside the NBME 26 score calculator.

At matched counts the NBME 26 score calculator sits zero to two points under Form 25: 50 wrong is 220 against 221, 70 is 198 against 199.

Almost all the movement between those sittings is you, not the paper, which makes the NBME 26 score calculator readable as a second opinion.

A rising estimate under comparable conditions is evidence the plan works. The NBME 26 score calculator cannot tell whether they were comparable.

A flat result across a fortnight of work says the plan needs changing, not extending, whatever the NBME 26 score calculator prints.

Two forms in the same week mostly measure fatigue, and the NBME 26 score calculator converts both into equally confident numbers.

With more than a fortnight left, the mid-dedicated checkpoint is the usual next stop after the NBME 26 score calculator.

Every form carries its own constants, so see how the seven forms differ before comparing raw counts with the NBME 26 score calculator.
