Studying for GSAE

Can anyone recommend any material/study guides to study for this exam? I’ve used the ones provided by the GS website, but I want to study more.

Thank you so much!

Sorry I just saw this. I actually took the GSAE and then the SAT a month later in case I wasn’t accepted into Columbia. The GSAE is based on the new SAT, so I recommend using SAT study material. I felt very prepared after using the College Panda SAT Writing book and UWorld.
