Ira Singhal, the topper of the 2015 batch, says that it is important for one’s basics to be clear in order to prepare for the IAS examination. One’s grasp of subjects should be strengthened during graduation, which will prove helpful while preparing for the examination. According to Singhal, if one gives the exam in a regional language, one’s use of the language should be impeccable, as no matter what the subject may be, the examiner isn’t lenient about the language and writing. However, if one is giving the exam in English, the examiner might be lenient with respect to grammar.
