Hi Costadina, The WS notebooks aren't really designed to simply try
to aid the memory of a large number of selected words in the short-
term in order to pass an exam. However, if it is necessary to cram
for exams the given WS method does offer a reasonable solution - but
one which will probably only produce similar results as learning with
ordinary lists or cards. WS is more about long-term real vocabulary
development---and encouraging students to develop good grammar habits
along the way.
Hope this helps
Best wishes
Will
