For college applications, prizes / certificates won till what grade are considered valid? [As in for example, 9th grade or older, 8th grade or older], or is it worth putting in most of the significant achievements that have been attained?
Short answer: I think any age when you earn a certificate or prize should be fine to put in your college essay. But if you are going to put it on your extracurricular activities, that is not a good idea to put anything lower than 9th grade as colleges mostly care about what you did in 9th-12th grade and not in middle school (8th and lower). Feel free to ask more questions!
