The Malmesbury Magistrate's Court, where the teenager appeared on Tuesday and is due back on Thursday.

The Malmesbury teenager arrested in an FBI-tipped raid for ordering American children to sexually abuse themselves and mutilate animals struggled so badly at school that a psychometrist recommended he be excused from writing his third-term exams that year.

His performance that year - 2024, when the report was compiled - was dismal, his marks in key subjects halving in a single term.

Afrikaans dropped from 75% to 49%, English from 86% to 43%, maths from 66% to 23%, natural science from 74% to 20% and digital technology from 76% to 16%.

The psychometrist recommended he be tested for autism, that he repeat Grade 8 and be taught in English rather than Afrikaans, his home language.
