This will give you a score that you need to convert into an IQ score, use this chart that will give you a centile, or you can figure it out yourself by using the mean and standard deviation:https://web.archive.org/web/20091229185320/http://www.cerebrals.com/tests/tri/Classeur1.pdf
and this website:https://www.iqcomparisonsite.com/iqtable.aspx

Do this test next:https://web.archive.org/web/20160611031125/http://www.cerebrals.org/iaw/index.php
Convert your raw score into a scaled score:https://docs.google.com/spreadsheets/d/e/2PACX-1vTAXAOLRctHeY1PAl0-cKQ9duaQU_yp8isN7_urJTKxGhmePI0yPvNHhcX1cVUcehseE_IXtP99QVb8/pubhtml

Then you generate the composite score. Let's say you scored 146 on the TRI52 and 139 on IAW, you would use this formula to generate your composite score: 100+(146+139-200)/1.685 = 150 "GAI"

Good luck, have fun, brainlets.
