The witness testifies that she has received a B.A. and Ph.D. in economics and business finance. On cross-examination concerning qualifications, the beneficiaries’ attorney asks, “Isn’t it a fact that you flunked out of college at the end of your freshman year?” to which the witness replies, “No.” The beneficiaries’ attorney then offers the registrar of the college that the witness attended to introduce a transcript of the college’s records to show that the witness studied only one year and was awarded no degrees.
