Hola,
I can't find "inmantado" (presumably the past participle of inmantar) in a dictionary.
That said I can find imantar - to magnetise. The reader definitely says inmantar and this is the spelling given in the introduction of words to look up. Are there two forms?
Secondly, the accent is misplaced on the word brújula at the top of the pages that appear as the test progresses.
Regards John
