There is almost whole change in company law except 4 old chapters of companies act '1956..though not much change in concepts.....so i would recommend u to better buy a new book of it.....so that u can remain clear on its contents at the examination day.....
Compared to Nov14 exam, addition is made to the extent of 80%. How will u study this 80% content. Content is huge so they dint release any supplementary for this. They have released new book.
