Hello dear friend as we know that institute has revised the syllabus for ISCA.also institute has issued practice manual for ISCA which is in question answer formate like compiler.i think we should not miss the reading of this practice manual and there are huge changes in chapter number 2nd & 3rd & apart from these there is huge changes so i think for these changes only we can refer the revised module and for rest of chapter we can refer the book we are already using.
alongwith new module and reference book reading of practice manual will be of great help.
All the best
Thanks
