ILTS Science: Biology (239) exam-day guide
ILTS Science: Biology (239) · Prepare for the day ahead.
Your checklist
Government-issued photo ID
Bring the original, unexpired ID (driver's license or passport) whose name matches your registration exactly. A photocopy or expired ID will not be accepted. Confirm the specific ID requirements and name-match rules with the test provider before test day.
Admission ticket or confirmation
Print or save your registration confirmation showing your test date, time, and test center. Some centers ask for the confirmation number; confirm with the provider whether a printed copy is required.
Test center address and route
Look up the exact address and plan your route in advance. Arrive early to allow for parking, security screening, and check-in. Confirm the reporting time on your admission ticket; it may be earlier than the scheduled start.
Layered clothing
Dress in layers because testing rooms can be warm or cold. Avoid clothing with large logos, slogans, or pockets that could complicate a security check.
Watch or timing awareness
Many computer-based tests display a clock, but confirm whether a watch is allowed. If a watch is permitted, use a simple non-smart watch; smartwatches and fitness trackers are typically prohibited.
Leave prohibited items at home or in the car
Phones, smartwatches, earbuds, notes, and study materials are generally not allowed in the testing room. Confirm the provider's policy on personal items and storage.
Snack and water for the break
If your test has a scheduled break, bring a small snack and water to have outside the testing room. Confirm break policies with the provider; some tests do not allow breaks.
Review the official test framework
Use the provider's published content framework to confirm the domains and approximate weightings. Do not rely on memory of the format; verify the current structure on the official site.
Practice with the official interface
If the provider offers a tutorial or practice test, complete it so you know how to navigate questions, flag items, and use the calculator or reference tools if permitted.
Confirm scoring and reporting
Check how and when scores are reported and whether a passing score is required. Policies vary; confirm with the provider rather than assuming.
Plan the day
Confirm your registration, test center address, reporting time, and ID requirements with the provider. Print your admission ticket if required. Do a final review of the official content framework and your weakest domain, using short focused practice sets rather than new material. Prepare your bag with ID, confirmation, layers, snack, and water. Protect sleep: aim for your normal bedtime rather than cramming.
Stop heavy studying. Review a one-page summary of key biology concepts and test-taking strategies. Check the weather and traffic forecast and plan your departure time with a buffer. Set two alarms. Eat a normal dinner and avoid excess caffeine. Confirm that your ID and admission ticket are in your bag. If you use a calculator, confirm whether it is permitted and what type is allowed.
Eat a normal breakfast and hydrate moderately. Arrive at the test center early, allowing extra time for check-in and security. Bring only permitted items into the testing room. Take a few slow breaths and read the directions carefully. If a tutorial is offered, use it to confirm the interface before the timed section begins.
Read each question fully and identify what is being asked before looking at the options. Answer every question; there is generally no penalty for guessing, but confirm the scoring rules with the provider. Flag uncertain items and return to them if time allows. Pace yourself using the displayed clock and leave a few minutes to review flagged questions. For biology items, eliminate options that misstate a process, use the wrong direction of cause and effect, or confuse similar terms. Stay calm if a question feels unfamiliar; move on and come back.
Rules to check
Bring original, unexpired government-issued photo ID with a name that exactly matches your registration. Confirm the provider's ID and name-match policy before test day.
Arrive at the test center at the reporting time on your admission ticket. Late arrivals may be denied entry; confirm the provider's late-arrival policy.
Do not bring phones, smartwatches, notes, or other prohibited materials into the testing room. Follow the test administrator's instructions for personal items and security screening.
Follow all directions from the test administrator. Unauthorized behavior, communication with other candidates, or possession of prohibited items may result in dismissal or score cancellation; confirm the provider's conduct policy.
Breaks, if offered, are typically scheduled and may be monitored. Confirm whether unscheduled breaks are allowed and whether the clock stops during breaks.
Scoring and passing standards are set by the provider. Confirm the current passing score, score reporting timeline, and retake policy on the official site rather than relying on secondhand information.
If you need testing accommodations, request them well before test day and follow the provider's approval process. Confirm deadlines and documentation requirements with the provider.
