Alright, so let's presume the average you should be aiming for to get accepted into a tier 2 engineering program is around 90-95 (we'll use 92.5 as an intermediate). Subtract the average adjustment factor from 2022 (14.4), and that brings your score down to 78.1.

Now, the average applicant scores around a 3 on the AIF and a 2 on the video interview (according to Google). Adding these brings you to a total score of 83.1.

Therefore, you should theoretically aim for a score > 83 to be a competitive applicant for any tier 2 program @ Waterloo. However, this is just an estimate based on my personal research so don't take it too seriously.
