some unit assessment strucutres suck..im doing OB and its supposed to be notirious for bringing out failures..they said that some wen tinto the exam already failed becoz of their assessments and they werent told what tha tthey were gonna fail. so i heard that half the class was failed but managed passess coz of scaling.
i dunno if its true, sources sometimes arent true at all...
relevance? urrr assessments structures fro some units are easy and make sure you will at least pass while others are more demanding.
