Hi! Compiler is a compiled version, chapter wise, of the suggested answers of various attempts. Right? However, the compiler on the institute website only consolidates questions till Nov 2014 attempt, there is no updated version. Does a good scanner cover all questions until Nov 2017? Please let me know the name of the publication for the same. Do I choose a scanner over a compiler?
