Lens Diagnostic
The Forum Lens Diagnostic score report offers Forum tutors, students, and families insight into test performance and prep recommendations available nowhere else. Our diagnostic reports are the industry standard: used by thousands of students since their creation, they break down performance to show families and tutors how to target prep for maximum impact. We don’t show just what a student got wrong, but “why” they got it wrong—and what they should focus on. Want to learn more? Read about our diagnostics below.

Ranked Recommendations
For all supported tests, we analyze test contents across over 50 categories and highlight patterns in students’ errors in both broad topics and granular subtopics. Then we rank these topics by the points students lost—so that prep can target the areas that will produce the biggest score gain.
“Uncertain” and “Rushed” Question Tags
Students who guess on questions will get 25-50% of them right. That’s a loss of 25-50% of data about key challenges. We resurface those by letting students mark when they were certain and/or when they rushed.


Uncertainty Analysis
We analyze answers against our proprietary tags to show whether issues are due to anxiety, content gaps, or careless errors. Did a student mark their wrong answers as confusing? Probably content gaps. Or did they not mark them at all? Likely careless errors.
Comprehensive Score History
Our reports visualize the entire prep process, spanning mock tests as well as practice sections assigned for homework. Does your student have anxiety or endurance issues? You’ll see that visualized in the difference between homework scores and full mock test scores, and Forum tutors will provide support to address these gaps early on.
