"Non-programmable calculators with no text-retrieval capacity are allowed.
Calculators that have a full alphabet on the keyboard are not allowed."

That is the only information the university would give regarding to calculator, there is no list of approved of calculators or anything. And as you can see the statement is vague regarding to what is programmable, the only clue it gives is the input and output of texts.

I asked the professor of the faculty about the acceptability of BA II plus in exams, he simply reply that "if the calculator is programmable, then no" and repeated the university policy. So it obvious that he does not know about the BA II plus and I am here confused about whether the BA II plus is "programmable", and it is left to my interpretation.
