We mostly did diy. Our start-up preparation was as follows.VR
: We started with Bond assessment books, then did Susan Daughtry techniniques book 1-4 and thereafter, IPS practice papers. Note SD technique books cover 35 types, where-as GL tests 21 types, so SD books are not needed as such; however, we found them useful in our preparation.
Have you also seen Patricia's post - extremely useful.viewtopic.php?f=3&t=30178NVR
: We used Bond assessment books and then Athey. At a later stage, we came across AE workbooks, which could be used instead of Bond assessment books.
