Academic Index Question

<p>Hey. I was just wondering if colleges still use the AI these days and if their method similar to the AI system provided at this website. Also, my school doesnt rank so i had to try and use the gpa system, and it said (4.0 scale, Weighted if Avail). So does that mean i should give my weighted avg? if it's weighted i would have a 98 which is 4.3 and above and that helped me a lot. my unweighted is 95.5, but our school sends weighted scores.</p>
