JPM4 exam review, second round, 2024, self-reading version, it is not necessary to take private lessons, you can take them | Dek-D.com

****Warning: Both topics. Don't put the points in order. Open and run. Whatever you can do, please****

Mathematics (4 parts)

Part One: Public Content Launch. Try to get each one of them. It's not really difficult. As far as I can remember, there will be

• Equation —> Find the value of x from the equation.

•Exponents —>Use simple division and multiplication properties. Make the base even. Then compare the exponent to the other side (here it will be a quadratic equation, then discover the value. The question asks about negative values)

•Percent —> One drug will have 70% remaining effectiveness of the initial dose after 1 hour. Give the 300 mg starting dose at 8 a.m., and ask at 11 a.m. How many mg of the drug will remain in the patient's body?

•Area—> Find the perimeter of the equilateral triangle. It gives the area of ​​an equilateral triangle.

•Quadratic equations—> If you have an equation that says one of the solutions for x is 3, you must find another answer for x. But there is also the letter k. This is a difficult secret to see. But try replacing x=3 first. Then separate the factors I can think of (I can't remember).

The first part contains 8 questions. 16 points (2 points per question.) That's all I remember, haha, but it's not really that hard. I want you to collect all eight items.

Part Two: Wow, this part is very difficult for us. Each question has 3 points. I can’t remember how many questions there are. Try to find things that can be done first. I feel like I can do 3-4 things.
There are probably conditions available. I didn't quite understand the question, so I skipped it.

• Spray paint, knowing how many colors to use. How many types can be made using the least amount? There are conditions available.

•Trigon—> There are two questions. The first question is presented in the form of an equation and then find the value (shown in degrees). Very simple.

Second, make it a trapezoid. He wanted to use steel to surround him. Ask how many inches long is the minimum requirement?

• Geometric Shift —> It turned out similar (just like this 55) to what happened the first time last year.

Question from P'Rakdee

Part 3: This part is very interesting. It is an invisible article. Completely different from the first round. It's really fun to read. Try to calm down and focus on reading to understand the meaning. I will definitely understand. Initially we were going to get rid of this part (almost), so don't get rid of it.

This part has 3-4 large points.

Part 4: Show how to do it, there are 3 elements

1. Inequality + equation (very easy) —> Let a be the smallest answer in this inequality. Let b be the answer to this equation. Find the value 2a-b. The answer is not pretty. Stay tuned. This question is worth 7 points.
2. Size —> conical or cylindrical, not sure. Suppose it is a cone. It is in the shape of a pyramid with a square base. All sides are close together (the base of the circle is in the middle). Find the height and length around the base of the pyramid. Ask 3 questions: Find the radius of the base of the circle. Find the volume of the cone. Find the volume of the pyramid after….(anything) Is this the highest level? Or are they all equal to 7? For me, this point is difficult, as I am confused.
3. Quartile —> Give a box plot (or not) then find Q1, find Q3, find the median. I can't remember the details of the problem. But this is not difficult. But I was careless and couldn't calculate the numbers. Number 55 is very scary

Sciences

Let's get 3 groups together. Try to manage your time. There is one set containing only 6 questions. But I feel like it's too much haha ​​He came out in the same style as last year. I advise you to read what old people wrote on dek-d, it really helps a lot, and is very accurate.

Physics

• Right line movement —> vt graph asks about average speed. Average Speed ​​The greatest acceleration is in the range of ___ seconds to ___ seconds

• What ball position has the most potential and most mobility?

Work + Power —> Have the child climb a slide 3 meters high with a line at the 1.2 meter mark, then the 2 meter mark. Ask work and power. I feel like the question has more details than this. But I can't remember much anymore.

• Electricity —> Ask about electrical circuit symbols. We have a diode and a fixed resistor. There are articles that explain things like….it helps convert electrical current flowing from alternating current to direct current. I can answer that it is a diode. Another question asks about electric current. Potential difference, resistance

• Mirror/Lens —> Find focal length.

•Waves—> This question is very basic, there are two questions, they ask about wavelength and frequency as well.

•Beam —> It's not difficult at all ******

biology

• It is an experiment on cells (mark true/false) in which an image of a potato soaked in water appears… soaked red blood cells. There is another one as well. Ask if the water the potatoes are soaked in is distilled. I asked if it would grow and break. Asked if it is Hypo/Hyper/ISO

• Give a picture of the cotyledon. Ask which picture represents the structure of the root and stem.

•Give a picture of the brain + a picture of the respiratory system + a picture of the excretory system (kidneys, ureters) and then talk about the Corona virus. This one is very easy. This Covid, you can read from the picture and answer, give the highest score, ask what people eat, which one will be the candidate first. When you get coronavirus, you feel like you can't remember things slowly. What part of the brain does it come from?

• Give the karyotype. Then he asked about the type of illness.

It came out similar to last year.

Chemicals

• Chromatography —> Find the substance with the highest polarity. Let it be an experience. Turmeric was released. What substance is absorbed best? It can move that far.

• Continue adding turmeric powder to the water. What is this step? When the setting time occurs, separation occurs, i.e. crystallization or precipitation, mark.

• Gives a colorless solution. If they are separate, how should they be separated?

• Give the nuclear symbol, it has a positive charge 2. Give the electron, give the mass number, find the neutron (easy).

• It is a table of elements abcde, giving the atomic number. Considering the different properties like electrical conductivity, boiling point, and melting point, ask which of them is suitable for making electrical wire covers. What is a metal, and what is a nonmetal, that is in the same group as element B? Write the arrangement of electrons, such as 2 8 8 3.

Landslides

• Acidic soil —> article available. Steps to balance chemical equations. Asked: What type of acid is formed?

• Acids and bases —> Write and fill out the table. If this substance changes to this color, what is its pH? Then summarize everything from the table. In which range does the pH fall?

Greenhouse gases

• Acid rain -> Chemical equations – Balancing chemical equations.

•The atmosphere of our world—> Give us the news: If a pilot wanted to search for survivors of a building collapse, which floor should he fly to? Ask which layer of nitrogen gas is largest and lowest if we continue to move away from Earth. What gas will gradually decrease?

It came out similar to last year.

‍️‍️Some exam questions may not be exactly the same. Some details may be missing. Some points have been forgotten. Some questions may be mixed with the Michigan State University test. Sorry‍️‍️ The exam has the same basic content every year. I advise you to go and look at what the old people wrote about. Keep fighting.️
