Regarding OG ,I think questions are little be simple but as XY said ,most important things are not the questions but the explaination selected by ETS.In OG 11th,explainations on the SC party have been improved and some moderate questions have been added into OG.So OG is very important. GWD is a package of questions more difficulty than those in OG.But many of them are real questions in the test.So GWD+OG is a perfect combination. |
