Guys if you are going to write answer don’t write it out as a,b,c, or d because each test has its answers swapped to be in different places! Were in this together guys so always help each other out! A few tips to try to avoid jiskha so you can get more confidence in test taking is take notes and try not to search up a answer, instead search up why something happens or how to do the type of math formula, good luck this 8th grade year guys!
