Wrong answer keys

The printed answer is wrong, no option is correct, or more than one is. Every question is solved again without looking at the key.

Independent solutionI ve IIPrinted keyE

Why it’s wrong: Grafikte kök 10⁻¹⁰, tomurcuk 10⁻⁸ dolayı, gövde 10⁻⁵ M derişiminde en iyi büyür. I doğru: her organın kendi en iyi değerine kadar derişim artışı gelişmeyi artırır. II doğru: kök gelişiminin azaldığı aralıkta gövde büyümesi hızlanır. III yanlış: belli bir değerden sonra derişim artarsa duyarlılık azalır, gelişme durur. Doğru yanıt “I ve II”dir; bu seçenek yoktur, anahtarın E’si yanlış olan III’ü de doğru sayar.

Suggested fix: III. yargı “kök, gövde ve tomurcukların duyarlılığı azalır” biçiminde düzeltilip anahtar E bırakılmalı; ya da seçeneklere “I ve II” eklenip anahtar o seçenek yapılmalıdır.

Not just typos, content errors too

A wrong key found after printing means an errata sheet, a reprint and reader complaints. We look for these errors under four headings.

Wrong answer keys

The printed answer is wrong, no option is correct, or more than one is. Every question is solved again without looking at the key.

Factual and terminology errors

Definitions, rules and table values are checked against Turkey’s Maarif Model curriculum.

Figure and chart errors

A missing axis label, a concept map built backwards, a figure that contradicts the text.

Spelling and punctuation

Typos that don’t change the meaning are listed in a separate table, with their pages.

The reasoning comes with every entry; your editor makes the call

The audit is done by AI models. It doesn’t replace your editor; it gives them a second pair of eyes that has solved every question in the book again.

Only for the audit

We don’t use your files for anything else, and we don’t use them to train AI models.

  • Reasoning in writing. Every entry gives what the book says, why it is wrong and a suggested fix. For answer key entries, the independent solution sits next to the printed key.

  • When we’re not sure, we say so. Debatable entries are marked “unsure”, with a note on what would settle them.

  • What matters most comes first. Entries are sorted by severity: wrong keys at the top, minor wording issues at the bottom. Typos get a table of their own.

  • Delete whenever you like. Once you’ve downloaded the report, you can delete the audit and all its files from your account.

  • Non-disclosure agreement. We sign NDAs with publishers covering their book files. Just write to us.
