Hello,
A friend of mine is planning to take the test early next year.
He asked me if he should be waiting for the new edition of the books to release.
I think it's not worth wasting time waiting for a new release!, as I don't feel that the 4th (or 5th edition...infinite :) ) would have a large difference than the existing one.
Would you be kind enough to let us know, what would be the difference (if at all) at the core of the next edition to come, or if it's 'safe' for him to buy the current edition and get started.
Rgds,
Achu.
