A synonym is a word that has the same or nearly the same meaning as another. 'Joyful' shares the positive feeling conveyed by 'happy.' The other options express different emotions. .
Solve for x: 2x + 3 = 11.
6
4
3
5
Subtract 3 from both sides to get 2x = 8, then divide by 2 to find x = 4. This is a basic linear equation. Understanding these steps is key for algebraic problem solving. .
What is often called the powerhouse of the cell?
Ribosome
Mitochondria
Nucleus
Golgi apparatus
Mitochondria generate most of the cell's supply of ATP, used as energy. Because of this role, they are called the cell's powerhouse. They have their own DNA and double membrane. .
Identify the direct object in the sentence: 'She reads a book.'
Book
Reads
She
A
A direct object receives the action of the verb. In this sentence, 'book' is what is being read, so it is the direct object. 'She' is the subject and 'reads' is the verb. .
What is the slope of the line passing through the points (1, 2) and (3, 6)?
2
4
1
3
Slope is (y? - y?) / (x? - x?) = (6 - 2) / (3 - 1) = 4/2 = 2. The slope measures the rate of change along the line. It's a key concept in coordinate geometry. .
What is the chemical symbol for gold?
Au
Ag
Go
Gd
The symbol 'Au' comes from the Latin word 'aurum' for gold. Chemical symbols often derive from Latin names. 'Ag' is silver and 'Gd' is gadolinium. .
Which sentence is punctuated correctly?
I cant wait to see the movie, she said.
"I can't wait to see the movie" she said.
"I can't wait to see the movie," she said.
I can't wait to see the movie she said.
Direct speech requires quotation marks around the spoken words and a comma before the closing quote if dialogue tags follow. The correct form is "I can't wait to see the movie," she said. .
What is 15% of 200?
20
30
25
35
To find 15% of 200, convert 15% to decimal (0.15) and multiply by 200 to get 30. Percentages are a common way to express proportions. .
Which element has atomic number 1?
Oxygen
Helium
Lithium
Hydrogen
Hydrogen has atomic number 1 because it has one proton in its nucleus. It is the lightest and most abundant element in the universe. .
Evaluate the integral from 0 to 1 of x² dx.
1/3
1
2/3
1/2
The integral ??¹ x² dx = [x³/3]?¹ = 1³/3 ? 0 = 1/3. This is a standard power rule application. Definite integrals compute area under a curve. .
What is the standard acceleration due to gravity on Earth (in m/s²)?
9.8
10
9
9.2
Standard gravity on Earth is defined as 9.80665 m/s², commonly rounded to 9.8 m/s². It represents the acceleration objects experience when falling. .
Choose the correct form to complete the sentence: 'If I ____ you, I would apologize.'
be
am
was
were
In hypothetical statements about the present or future, English uses the subjunctive mood 'were' with 'I'. So 'If I were you' is correct. .
Solve the system: x + y = 5 and x ? y = 1.
x = 1, y = 4
x = 4, y = 1
x = 3, y = 2
x = 2, y = 3
Adding the equations gives 2x = 6, so x = 3. Substituting back into x + y = 5 yields y = 2. Systematic solving is key in algebra. .
Which law is described by the formula F = ma?
Newton's First Law
Newton's Third Law
Law of Universal Gravitation
Newton's Second Law
Newton's Second Law states that force equals mass times acceleration (F = ma). It quantifies how force changes an object's motion. .
Identify the sentence written in passive voice.
The cat will chase the mouse.
The cat chased the mouse.
The cat is chasing the mouse.
The mouse was chased by the cat.
Passive voice occurs when the subject receives the action. In 'The mouse was chased by the cat,' the mouse is acted upon. Active sentences place the subject before the verb. .
What is the derivative of sin(x)?
-sin(x)
cos(x)
sin(x)
-cos(x)
The derivative of sin(x) with respect to x is cos(x). This is a fundamental result in differential calculus. It's used widely in physics and engineering. .
Evaluate the limit as x approaches 0 of (sin x ? x) / x³.
1/6
?1/6
?
0
Using the Taylor series for sin x ? x ? x³/6 + …, substitute into (sin x ? x)/x³ to get ?1/6. This limit uses series expansion for accuracy. .
Which figure of speech is used in 'The wind whispered through the trees'?
Simile
Metaphor
Personification

  2. Use a Periodic Table Mnemonic -

    Memorize the first ten elements with a phrase like "Little Betty Boy Caught Nine Peaches Now" (Li, Be, B, C, N, O, F, Ne). This trick simplifies recall of atomic numbers on science and chemistry questions. (Source: IUPAC)

  3. Solidify Subject-Verb Agreement -

    Remember that singular subjects take singular verbs ("The class is"), while plural subjects take plurals ("The classes are"). Practice with mixed nouns and pronouns to avoid common grammar pitfalls on the English section. (Source: Purdue OWL)

  4. Apply the Memory Palace Technique -

    Visualize placing facts or formulas in distinct "rooms" of an imagined building to improve long-term recall. This method, backed by neuroscientific research, boosts performance in general knowledge quizzes. (Source: Britannica)

  5. Practice Syllogistic Logic -

    Work through basic syllogisms like "All birds have feathers. Penguins are birds. Therefore, penguins have feathers." Regular drills sharpen critical thinking skills essential for multi-subject tests. (Source: Cambridge University)
