What you get
Built for the way the exam scores
Multi-select scored by the official rule
Partial credit, neutral options and the zero-credit rule, on every multiple-answer question.
Prescription tasks
Medication, strength, quantity, dose, loading dose and frequency. The official key is not published, so each task is scored out of 4 on our own training rubric, with a breakdown.
Adaptive practice
Sessions lean toward your weakest content areas and the items due for review.
A full-length practice exam
Five timed sections in the official order, with your clock kept on our server.
Practice under the exam's own rules
The DLOSCE has its own scoring rules. On a question with one or more correct answers, a single incorrect selection earns no credit for the whole item, correct options can carry partial credit, and neutral options change nothing.1 Every multi-select question in this course is scored exactly that way, so you learn when to commit to an option and when to leave it out.
- Patient Box cases. Most questions start from a fictional patient's Patient Box: history, medications, vital signs and findings written in words, with allergies listed when the patient has them, across pediatric, geriatric, special-needs and medically complex patients.2
- Longer option lists. Many diagnosis and management questions list several plausible choices in a logical clinical order, as the exam does, rather than a fixed set of four.
- Prescription tasks. Choose the medication, strength, quantity to dispense, number per dose, loading dose and frequency, the fields the exam asks for.1 The official scoring key is not published, so answers are scored on Dentovio's own 4-point training rubric: one point each for strength, quantity, dose with loading dose, and frequency, and 0 for a medication no accepted regimen supports or a daily total above the task's maximum.
- An explanation for every option, with the controlling guideline or reference linked at the item.
Study what you need, not just more questions
- Adaptive practice leans toward your weakest content areas and the items due for review.
- Topic drills cover all nine official content areas: choose any multiple-choice area and its subtopics, or drill the antibiotic and analgesic prescription tasks.2
- A review queue brings back missed and partial-credit items on an expanding schedule.
- A full-length practice exam follows the official five-section order and timing, with the clock kept on our server so you can resume.2
What it does not include
The real exam uses 3D models; this course states findings in words, so practice the model controls with the official ADEX tutorial.3 Every question is original. None is recalled from the exam, and none comes from official practice materials. Practice percentages are not DLOSCE scaled scores and do not predict a result. Dentovio is independent and is not affiliated with or endorsed by the ADA, the JCNDE or ADEX.
