Time Management Strategies

Effective time management is crucial both during your preparation for the TEAS Science section and on the exam day itself. Here are some strategies to help you manage your time efficiently:

During Preparation

Set a Study Schedule: Allocate specific times for studying each topic, ensuring a balanced approach that covers all areas. Use tools like planners or digital calendars to keep track of your study plan. Additionally, consider incorporating our TEAS Cram Course into your schedule. This course offers a structured and intensive review of key topics, tailored to fit into your available study time, ensuring that you cover all necessary material efficiently.

Prioritize Topics: Focus more time on topics you find challenging while maintaining a consistent review of those you are more comfortable with.

Practice Timed Tests: Regularly take TEAS Science practice tests under timed conditions. This helps in building speed and accuracy, and you’ll get a feel for the pace you need to maintain during the actual exam.

On Exam Day

Allocate Time Wisely: Be aware of the time you are allocating to each question. Do not spend too much time on any single question. A good rule of thumb is to spend about a minute per question, adjusting slightly depending on the complexity.

First Pass and Review Strategy: On your first pass through the exam, answer questions you are sure about and mark those you are unsure of for review. After completing all the questions, go back to the marked ones. Remember, you can return to questions within the same section, but once you start a new section, you cannot go back.

Stay Calm and Focused: If you find yourself spending too long on a question, take a deep breath, mark it if necessary, and move on. It’s better to come back to it with a fresh perspective than to lose valuable time.
