Ipc (new) study module vs ipc(old) study module

I am a ipc(old)course student.I have to appear in Cost & FM,Tax,IT& SM  in upcoming may 19 ipc (old)exams.I just checked ipc(new )study material of these two papers (tax material is same for old and new ).In new study material  each concept  is explained with examples ,charts .At the end of each chapter MCQ questions are also given.Can i go through ipc (new ) material too though i have to appear in ipc(old) ?Our motive is not only to pass but to gain knowledge too.Am i right ?
