I'd put that as major success as well. you might devalue it because it's one of god-knows-how-many, but the reality is you've gained control over the material/ elements. Some folks freeze in exams, so just to get through them is really major battle and other folks eat them up. Sometimes I did well and sometimes I froze, just depended on class and style of exams. Sitting an exam during or shortly after bad event or circumstances such as seriously bad medical news, death in family, dog croaking, boyfriends/girlfriend absconding with personal property, etc all should get heavy mark-ups, but never do. Congrats
