Tips and Test Prep for passing the CLEP Natural Science ()

We've compiled a list of study tips to help you tackle your test preparation and ace your CLEP Natural Science exam. Whether you are just starting your journey with studying or need a bit of inspiration to refresh your routine, these tips are designed to give you the edge you need to pass your exam with flying colors.

Exam Plan are you ready

Create a CLEP Natural Science Study Plan

  1. Review exam requirements: Check the College Level Examination Program's requirements for the CLEP Natural Science exam to make sure your studying approach suits the exam's format and content.

  2. Identify your learning style: Everyone learns differently, and most of us learn best when we get the same information in a variety of delivery methods. Identify the learning styles and studying approaches that best work for you to maximize your study efforts.

  3. Create a study schedule: Set aside dedicated study time each week to ensure you're making consistent progress. You might consider having dedicated sessions for each content area, such as a day or week dedicated to different sections of the exam. Plan to take practice tests at regular intervals to chart your progress.

  4. Take CLEP Natural Science practice tests: Practice exams will give you an idea of the types and format of questions that you can expect on test day. Our practice tests replicate the CLEP Natural Science exam format, with 120 unique question on each practice test. By getting you comfortable with test-taking and getting the most out of your practice tests, our practice tests can help you ace your exam on test day.

General CLEP Natural Science Study Tips

  • Find a study partner: Do you have a colleague, classmate, or friend who is also pursuing a CLEP Natural Science certification? Studying with a partner can help keep you accountable and provide an opportunity for discussion and clarification. Practicing test questions together might be an opportunity for some friendly competition too!

  • Take breaks: Regular breaks can help prevent burnout and improve retention of information. As you study, give yourself regular pauses to decompress and process what you are learning.

  • Stay organized: Keep your notes, study materials, and practice exams organized to avoid feeling overwhelmed. Whether you prefer a physical or digital studying environment (for instance, taking notes by hand versus typing them into your Notes app), a tidy space and methodical approach will help you stay focused on your test prep.

  • Take care of your physical health: A healthy body leads to a healthy mind, so make sure your test prep routine also prioritizes exercise, nutrition, and sleep during your study period. During the lead-up to your CLEP Natural Science test day, don't cram - get plenty of rest so your brain is sharp!

  • Utilize test-taking strategies: Techniques, like the process of elimination, can help improve your chances of success. If you are stuck on a difficult practice exam question, try to rule out one or two options to narrow down the possible answer. Exam Edge's test-taking system allows you to flag practice test questions you want to return to - use these features to your advantage!
By incorporating these study tips into your preparation process, you will be well on your way to success with the CLEP Natural Science exam. Remember, success requires dedication and hard work - don't give up!

CLEP Natural Science - Study Plan Tips Sample Questions

Crop productivity starts to decline when the leaves begin to wilt mainly due to which of the following?

Correct Answer:
stomata close and prevent carbon dioxide from entering the leaf.

crop productivity is significantly influenced by the physiological state of the plants, particularly the leaves, which are critical for photosynthesis. photosynthesis is the process by which plants convert light energy into chemical energy, using carbon dioxide (co2) and water to produce glucose and oxygen. this process is vital for plant growth and crop yield.

the question focuses on the impact of wilting leaves on crop productivity. wilting occurs when there is insufficient water for the plant's needs. water is crucial not only for maintaining plant turgidity but also for the physiological processes inside the cells. when plants experience water stress due to inadequate water supply, several responses are triggered to conserve the remaining water.

one of the primary responses is the closing of stomata, which are tiny openings on the leaf surfaces that allow for gas exchange between the plant and its environment. stomata are flanked by guard cells that swell or shrink due to changes in their turgor pressure, directly influenced by the plant's hydration levels. under water stress, the guard cells lose turgor pressure and become flaccid, causing the stomata to close.

the closure of the stomata reduces water loss from the plant through transpiration, which is a necessary trade-off to conserve water. however, this closure has a significant downside—it also prevents the uptake of carbon dioxide from the atmosphere. since carbon dioxide is a critical substrate for photosynthesis, its reduced availability directly impacts the plant's ability to synthesize glucose, thus affecting overall energy production and growth.

consequently, when the stomata are closed, and co2 cannot enter the leaves, the rate of photosynthesis declines sharply. this reduction in photosynthesis leads to decreased crop productivity, as the plants are not able to produce sufficient biochemical energy and biomass. therefore, the correct answer to why crop productivity starts to decline when leaves begin to wilt is that the stomata close and prevent carbon dioxide from entering the leaf, thereby reducing photosynthesis and ultimately crop yield.

Two plane mirrors are placed at right angles to each other. A ray strikes the first mirror at an angle of incidence θ so that it is also reflected from the second mirror. What will be the ray reflected from the second mirror? 

Correct Answer:
it will be parallel to the ray incident on the first mirror.

when two plane mirrors are placed at right angles to each other and a ray of light strikes one of the mirrors, the behavior of this light ray can be analyzed using the laws of reflection. according to the law of reflection, the angle of incidence (the angle at which the incoming ray hits the surface) is equal to the angle of reflection (the angle at which the ray departs from the surface).

in this specific scenario, let's consider a ray striking the first mirror at an angle of incidence, θ. this ray is reflected off the first mirror at the same angle, θ, relative to the normal (the perpendicular to the surface at the point of incidence). since the ray strikes and reflects off the first mirror, the total angle made with the surface of this mirror is 2θ (θ incidence + θ reflection).

next, this reflected ray proceeds to strike the second mirror. the critical observation here is that the mirrors are placed at a 90° angle to each other. therefore, the angle of incidence for the second mirror is 90° - θ. this is because the incident ray to the second mirror makes an angle of θ with the line that would be perpendicular to the second mirror if the mirrors were aligned. following the law of reflection again, this ray is also reflected off the second mirror at an angle of 90° - θ.

considering the movement of the ray from its original direction (incident ray on the first mirror), through its reflection off the first mirror, to its incidence and reflection off the second mirror, the total deviation from its original path is 180° - 2θ (90° - θ from the normal of the second mirror, doubled as it is reflected). this means the ray, after reflecting off the second mirror, is traveling in a direction that is parallel to its original incoming direction but in the opposite direction. essentially, the ray retraces a path parallel to its initial approach but reversed.

it is also noteworthy that such a configuration of mirrors (at right angles) can generate reverse images. this is because each reflection involves a reversal of the image along the axis perpendicular to the mirror. when two such reversals occur in orthogonal planes (due to the right angle between the mirrors), the final image observed will appear reversed compared to what would be seen with a single plane mirror reflection.

in summary, when a ray of light strikes the first of two mirrors set at right angles, and then the second mirror, the ray that finally emerges is parallel to the ray that initially struck the first mirror, though it travels in the opposite direction. this setup is often used in periscopes and other optical devices to change the direction of light while maintaining the alignment of the image with the original object.
