OSAT Biological Sciences (110) exam-day guide
OSAT Biological Sciences (110) · Prepare for the day ahead.
Your checklist
Government-issued photo ID
Bring the exact ID the provider requires (typically a valid driver's license, state ID, passport, or military ID). The name on the ID must match your registration name exactly. If you have any doubt about which forms are accepted or whether a name discrepancy matters, confirm with the provider before test day.
Admission ticket / registration confirmation
Print or save your registration confirmation showing your test date, time, and test center. Some centers ask to see it at check-in, so have it accessible rather than buried in email. Confirm with the provider whether a printed copy is required or a digital copy is acceptable.
Know your test center location and arrival time
Look up the exact address and confirm parking or transit options the day before. Plan to arrive well before your scheduled start; late arrivals may be turned away at the provider's discretion. Confirm the required arrival window with the provider.
Review the current test-day policy page
Rules on personal items, calculators, scratch paper, and electronics change over time. Read the provider's current policy for your specific test before you travel. Treat any third-party summary as unofficial.
Confirm what personal items are permitted or prohibited
Most testing programs restrict phones, smartwatches, bags, and notes, often requiring them to be stored in a locker or left outside the testing room. Do not assume you can keep a phone on your person. Confirm the storage arrangements with the provider.
Confirm the calculator policy for this test
Calculator rules differ by exam and by section. Do not bring one unless the provider explicitly permits it, and confirm whether an on-screen calculator is provided. If you are unsure, confirm with the provider.
Plan for scratch materials
Many centers supply scratch paper or a dry-erase board and prohibit bringing your own. Confirm what is provided and whether you may bring your own writing instrument. Do not rely on bringing outside paper.
Comfort items that comply with policy
Layers, water, and snacks may or may not be allowed in the testing room; often they must stay in a locker and can be accessed only during breaks. Confirm the break and access policy with the provider before relying on them.
Medical or testing accommodations arranged in advance
Accommodations generally must be requested and approved before test day, with documentation. You cannot typically arrange them at the door. If you need accommodations, confirm the approval status with the provider well before your date.
A study plan for the final days, not new material
In the last 72 hours, prioritize reviewing your own notes, formula relationships, and high-yield biology concepts over starting new topics. Prepare a short list of concepts you repeatedly miss and review only those.
Rest and logistics plan
Protect sleep the night before, eat a normal meal, and avoid last-minute cramming that displaces rest. Set two alarms and arrange backup transportation. These are practical steps, not official requirements.
Know how scores are reported and when
Understand the scoring scale, passing threshold, and score report timing for this test by checking the provider's official materials. Do not rely on secondhand claims about cut scores or reporting windows; confirm with the provider.
Plan the day
Shift from learning to consolidating. Review your own summary sheets for core areas: cell biology and energetics, genetics and inheritance, molecular biology and gene expression, evolution and natural selection, ecology and population biology, and organismal structure and function. Practice a small number of timed questions to rehearse pacing, then review every miss and write the underlying concept in one sentence. Stop adding new resources. Confirm your test center address, arrival time, and what the provider permits you to bring.
Do a light review only: skim your one-sentence concept list and any diagrams or pathways you tend to forget. Prepare your ID, admission confirmation, and any permitted items in one place by the door. Check the provider's policy page once more for any last-minute change. Set alarms, plan meals and transportation, and go to bed at a reasonable hour. Avoid intensive cramming, which tends to cost more in fatigue than it gains in recall.
Eat a normal breakfast and hydrate moderately. Leave earlier than you think necessary to absorb transit or parking delays. Arrive within the provider's required window; late arrival can mean being denied entry. Leave prohibited items such as phones and smartwatches secured or stored as the center directs. Bring only the ID and permitted materials to the check-in desk.
Follow staff instructions for ID verification, sign-in, and any security screening. Store personal items where directed. If a rule is unclear, ask the proctor before the test begins rather than guessing. Note where the clock is and how much time you have.
Read each question fully before answering. Answer easier questions first if the format allows navigation, and flag difficult ones to return to. For biology items, identify what is being asked (mechanism, comparison, or prediction) before evaluating choices, and eliminate options that are factually wrong before choosing between the remainder. Watch the clock and reserve time to review flagged items. If breaks are offered, use them to stand and reset, and note whether the clock continues during breaks.
Note which topic areas felt weakest while the memory is fresh, in case you need to retake. Confirm with the provider how and when scores are released and what the retake policy and waiting period are. Do not attempt to reconstruct or share specific test questions; most programs prohibit disclosing test content.
Rules to check
Bring the exact government-issued photo ID the provider requires, with a name matching your registration. If your ID name differs from your registration name, confirm the resolution procedure with the provider before test day.
Arrive within the provider's stated arrival window. Candidates who arrive late may be denied entry or have their appointment forfeited; the specific cutoff is set by the provider, so confirm it in advance.
Do not bring phones, smartwatches, notes, or other unauthorized materials into the testing room. Store them as directed. Unauthorized devices or materials can lead to dismissal or score cancellation under the provider's rules.
Follow all proctor instructions and any security procedures, including sign-in, screening, and room rules. Ask before the test starts if any instruction is unclear.
Breaks are governed by the provider and may be scheduled or optional, and the clock may or may not stop during them. Confirm the break policy for this test rather than assuming.
Scoring, passing thresholds, and score reporting are set by the provider. Do not rely on unofficial cut scores or reporting timelines; confirm the scoring scale and release schedule with the provider.
Do not disclose, reproduce, or discuss specific test questions or content after the exam. Most testing programs treat this as a violation of the candidate agreement.
Accommodations must generally be requested and approved before test day with supporting documentation. If you need accommodations, confirm approval status with the provider well ahead of your appointment.
