Query: CD-ROM is buggy

Though the content of the book itself is not bad, the CDROM that is included with it and that is supposed to simulate a real GMAT CAT is >>>COMPLETE GARBAGE<<<.The timers on the questions are wrong. Instead of giving you 75 mins for each section, they give you 30 and 45 mins for the verbal and quant sections respectively.I noticed several of the questions in the quant section have incorrect answers programmed (e.g. the real answer is D but software is programmed for B) the skewing your test results.These are simply inexcusable errors that would have been caught with simple testing. Whoever was in charge of Quality Control for the CD should be fired for failing to do their job.
