Bought the book from the attesting , probably safest book to buy idk about other options . Test seemed easy and I was so sure I did pretty good but Study ! Math is easiest , very easy algebra stuff easy to get 100 . Honestly probably don ' t even need to study as long as you passed high school math . Though be careful and double check your answers just in caseScience hardest i felt like lot of anatomy was there idk though could be diff . for diff . testsReading and Language Usage Easier than SAT Probably would depend on your english level . If you ' re good at english probably easy . If not better study . <| sep |> I think that Yellow Diamond will be resolved peacefully and anticlimactically most likely through helping YD get over the loss of PD boo ! , but that will be immediately followed by dealing with the other two Diamonds not so peacefully . This way the CREWniverse can troll the fanbase with a false summit and pass on the message to children that inside every bad person , there ' s a good person who can be brought back through kindness and reason , but you can ' t get through to them all . Also , having YD side with the Crystal Gems would help with healing at least the physical effects of corruption , and would raise the intensity of the final confrontation with Home World all the more intense .
