What Students Are Saying
Real experiences from medical students who used the calculator and dashboard.
“I was consistently scoring in the 215–220 range and had no idea why. The dashboard identified Pharmacology and Pathology as my weakest areas and gave me a specific plan. Six weeks later I scored 231 on the real exam.”
“The exam countdown with the NBME testing timeline was a game changer. I always took NBMEs randomly — now I know exactly when to take each one. Scored 248 Step 2 CK.”
“I paid $60/month for Amboss and $40 for another analytics tool. This free dashboard does more than both combined. The NBME to real score correlation table alone is worth everything.”
“As an IMG, I had no access to advisors. The 9-hour optimized daily schedule and weak area tips literally replaced what American students get from their schools. Passed with a 219.”
“My NBME 25 score was 207. I used the dashboard every week, followed the weak area plan religiously. By NBME 28 I was at 224. Real exam came back 229. The prediction was spot on.”
“The percentile widget showed me I was already in the top 30% but I didn’t feel confident. Seeing the data helped me stop second-guessing and actually schedule my exam.“
