With the first semester results of Delhi University’s undergraduate courses out, teachers and students have found out that the to achieve the top O’ grade (‘outstanding’) in some subjects under the choice-based credit system (CBCS), students have to score over 100% marks, reports a leading English daily.This is just one of the many strange anomalies that were realised and confirmed by the university’s exam branch officials. <!– /11440465/Dna_Article_Middle_300x250_BTF –>The CBCS needs the examiners to convert absolute marks into letter grades and grade points through a UGC-devised formula. For getting an ‘O’ grade. students need to obtain marks equal or greater than the sum of the mean and 2.5 times the standard deviation. This method has made ‘O’ unachievable for the students of Biomedical Sciences, Biological Sciences and Biochemistry.Kirori Mal College Economics teacher Saumyajit Bhattarcharya used the UGC formula for 2013 scores in an optional paper written by 102 students. He realised that to achieve an ‘O’, they would have score 108 and for ‘A+’, they need 100 marks.He also found out that while students in First Year History most students got ‘O’, but in the more scoring paper Mathematics there was not a single ‘O’ grader. Instead, most of the students got B grade in the subject which Bhattarcharya says is due to the UGC grading method.Teachers also fear that this problem may affect other subjects too as a students’ grade is related to examinees across DU do and has little to do with individual performance. “A candidate’s grade depends on the performance of all DU students who took that exam. The minimum passing mark too is decided by the cohort. A standard 40% is meaningless,” said Rup Lal, dean of examinations.Marksheets stating one grade per paper which has a total evaluation of the exam, practical test and internal assessment which has lead to more confusion.Application form for re-evaluation asks for only marks obtained in theory. Also, marks of the exam, practical test and internal assessment are not made public.
