For SACE, everyone gets a score out of 20. Hypothetically, if I had these scores Skills and apps 30% = A+ Inevstigation folio 40% = A+ Exam = A+ Okay, so this would be equivalent to a 20 right? But lets say you didn't get straight A+ in investigation folio lets say you had 5 assessment tasks for investigation folio for 2 you got A for 3 you got A+ would this lower your score? Even if you got overall an A+ for the folio? Please help me I need a 20/20 and I have one A in this subject.

As far as I understand, SACE only looks at the overall grade for the unit - so as long as you still get an A+ for the 40% folio unit they don't care. However, I'm pretty sure you can still miss out on a 20/20 despite getting all A+ I'm pretty sure you need to get full or close to full marks in the final exam as well as A+ for skills & folio to get a 20. So what I'm saying is that if you just barely manage to get an A+ in the exam, you may still miss out on the 20 (however, you'll still get close eg. 19.9 or 19.8 assuming the subject isn't scaled back)
