In TrueLearn, you can specify any combination of new, incorrect, and/or correct questions. TrueLearn has some unique and useful tools regarding test creation that UWorld does not. This can also help students draw big-picture connections between individual questions, if they understand broadly what is being asked (a pathology question about cardiology disease processes, for example). This is probably why the search function is better. Each question is coded in several domains, including Specialty, System, Process, Discipline, Interdisciplinary areas, Competencies. Some rely just on buzz-word recognition (e.g., cigar shaped on microscopy for Sporotrichosis), and some require more thought, which we believe is appropriate and reflective of the NBME. There are one- and two-part questions as well. There is a mixture of single-step and multi-step questions in TrueLearn. The same test-taking strategies were applicable and the material is what one would expect to be covered in UWorld questions. Subjectively, when taking a TrueLearn test, it does feel very much like taking a UWorld test. TrueLearn questions are similar in difficulty, length, and complexity when compared with UWorld. TrueLearn ’ s most represented systems are GI (184 questions), Nervous system (171), Renal (135), and Blood/Lymph, which all have more questions than Cardiology (99). For example, the most heavily represented system in UWorld is Cardiology (365 of 2813 questions, or 13%), while TrueLearn focuses less on this system (99 of 2,234 total, or 4.4%). However, the focus of the TrueLearn question bank is slightly different than that of UWorld. This mean they have just under the number of practice questions provided by UWorld, who comes in at 2,813. The TrueLearn question bank has 2,234 questions in total.
