just a note. i emailed the lecturer and she says yes non-programmable calculators ARE allowed in the exam. This is contrary to the 203 tut-letter/exam, but correct in terms of the note on the myunisa exam-timetable. the lecturer has the final say, and the exam timetable confirms this.
if anyone wants to form a study group around INF425, give me a bell at 021 658 8000.
