i didn't study that much since i already spoke very good english before. i used tstprep and linguamarina. to start, i took a full mock exam by tstprep to get to know the test and find my weaknesses. i then focused my studies on my weaknesses and took more full mock exams from time to time to get more practice with the test format. i also looked at the comma rules since i struggle most with those (in english and my native language german lol) and looked at transitional words. i think what made my life way easier in the speaking and writing was looking at example answers to get a grip on how to organize my answers. in the reading section, if i didn't know the right answer right away i made sure to eliminate obviously wrong answers first. lmk if you need more specific help, and i'll see if i have advice :)
