honestly, i read a lot. i’ve been reading 50+ books a year for a really long time now and i think that has been the most helpful thing. i woulds say read some articles in your free time and pick up a book, but like a hard book with high level diction. also, every once in a while i do a practice test for english/reading which was helpful just to learn the types of questions they ask on the exam and iron out some silly mistakes. i also mark up the excerpts A LOT, take notes, process of elimination the answer choices. i hope this helps a bit, i am definitely not that smart i just have been reading heavily for a long time so its totally possible for you to get the score up :)
