****Warning: both subjects. Don’t put the dots in order. Open and turn. Whatever you can do, keep going *****
Mathematics (4 parts)
part 1: publish general content. Try to catch them all. It’s really not 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. Evens out the base. Then compare the exponent with the other side (here it will be a quadratic equation Then find out the value The question asks for a negative value)
•Percentage —> A drug will have 70% effectiveness remaining from the initial dose after 1 hour. Administer the initial dose of 300 mg at 8:00 am. Ask at 11am. How many mg of medicine will remain in the patient?
•Area—> Find the circumference of the equilateral triangle. Gives the area of an equilateral triangle.
•Quadratic equations—> Given an equation that says a solution of x is 3, you should find another answer of x. But there is also the letter k. This is difficult to see secretly. But try replacing the value x=3 first. So separate the factors It comes to mind (I don’t remember).
The first part has 8 questions. 16 points (2 points for each question) That’s all I remember, haha, but it’s not that hard. I want you to collect all 8 items.
part 2: Wow, this part is quite difficult for us. Each question has 3 points. I don’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.
Probability There are expected conditions. I didn’t quite understand the question so I’ll skip it.
•Spray paint, find out how many colors to use. And how many types can be made using the minimum quantity? There are conditions expected.
•Trine—> There are 2 questions. The first is given as an equation and then the value (expressed in degrees) is found. Very simple.
Second, make it a trapezoid. He wanted to use steel to surround it. Ask how many inches in length is the minimum required?
•Geometric Transformation—> It turned out similar (just like this 55) to the first time last year.
cr.Question from P’Rakdee
part3: This part is very funny. It’s an article I’ve never seen before. Completely different from the first round. It’s really fun to read. Try to calm down and concentrate on reading to understand the meaning. I will definitely understand. We were originally going to delete this part (almost), so don’t delete it.
This part has 3-4 important points.
part 4: show how to do it, there are 3 items
Science
Let’s take 3 sets together. Try to manage your time. There is a set that only has 6 questions. But I want it. It’s a lot, haha. It came out in the same style as last year. I advise you to read what the elders say on the dek-d website. It really helps a lot and is very accurate.
physics
•Right line movement—>vt graph requires average velocity. average velocity greater acceleration In the range from___seconds to___seconds
•Which ball position has the most potential and kinetics? The position that has both kinetic and potential.
•Work+Power—> Let a child climb a 10-foot slide with a rope at 4 feet, then 6 feet. Asking for work and power. I feel like the question has more detail than this. But I don’t remember much anymore.
•Electricity—> Ask about electrical circuit symbols. Ours has a diode and a fixed resistor. There are articles that explain things like…….it helps transform the electric current flowing from alternating current to direct current. I can answer that it is a “diode”. There is another question, which asks about electric current. potential difference, resistance
•Mirror/Lens—>Find focal length.
•Waves—> This is very simple: there are 2 questions that also ask for wavelength and frequency.
•Beam —> It’s not difficult at all ******
Biology
•This is an experiment on cells (tick true/wrong) that show the image of a potato immersed in water… Soaked red blood cells There is also another one. Ask if the water the potatoes are soaked in is distilled water. I asked if it would grow and break. When asked if it’s hypo/hyper/iso
•Give the image of a cotyledon. Ask which picture represents the root structure and trunk.
•Give a photo of the brain + a photo of the respiratory system + a photo of the excretory system (kidneys, ureters) and then tell about COVID. This is very simple. This Covid, you can read from the image and respond. Give the highest score. Ask what people eat, what will be the first filter. When you get infected with Covid, you feel like you can’t remember things slowly. What part of the brain does it come from?
•Give a karyotype. Then she asked what kind of disease it was.
It came out similar to last year.
chemist
•Chromatography—> Find the RF of which substance has the highest polarity. Let it be an experiment. Turmeric substance released Which substance is best absorbed? It can go this far.
•Proceed by adding the turmeric powder to the water. What is this step? When the setting time expires, separation occurs, i.e. crystallization or the precipitate, sprouting.
• Provides a colorless solution. If they are separate, how should they be separated?
•Give the nuclear symbol. It has a positive charge of 2. Give the electron. Give the mass number. Find the neutron (easy).
•It is a table of abcde elements showing the atomic number. Given the various properties such as electrical conductivity, boiling point, melting point, ask which one is suitable for making electrical cable coatings. Which is a metal, which is a nonmetal, which is in the same group as element b? Write the arrangement of the electrons, for example 2 8 8 3.
Landslides
•Acid Soil—>One item is provided. steps balancing chemical equations When asked what type of acid was formed.
•Acids-bases—> Write and complete the table. If this substance changes to this color What is pH? Then summarize everything from the table. What range is the pH in?
Greenhouse gases
•Acid rain–> Chemical equations Balancing chemical equations.
•Atmosphere of our world—> Give us the news: If an airline pilot wants to search for survivors of a building collapse, what floor should he fly to? Ask yourself which nitrogen layer is the largest and smallest if we continue to move away from the Earth. Which gas will gradually decrease?
It came out similar to last year.
️️Some questions on the exam may not be exactly the same. Some details may be missing. Some points have been forgotten. Some questions may be confusing for the MSU exam. Sorry️️ The exam has the same basic content every year. I advise you to go and see what the elders have written. Keep fighting.️
