TL;DR:
Read the question before the passage, so you know what evidence to look for while you read.
Predict an answer in your own words before you look at the choices.
Eliminate choices that the text does not support, and pick the one that matches your prediction most closely.
Many students read a Reading and Writing passage like a story: start at the top, read to the bottom, then look at the question and hunt for something that sounds right. That approach runs out of time and leaves you choosing between answers that all sound plausible. A better habit is to treat each question as a small task with one piece of evidence to find.
Read the question first
Before you read the passage, look at the question and find two things: what kind of task it is, and where in the passage it points. A question about a word's meaning points to one sentence. A question about the main idea points to the whole passage. A question about grammar points to a single sentence and its punctuation.
Once you know the task, read the passage with that task in mind. You are not reading for everything. You are reading for the evidence the question needs.
The method, step by step
Read the question stem: Ask yourself what the question wants: a conclusion, a word in context, a transition, a grammar fix, or the best supporting detail.
Find the relevant lines: Locate the sentence or lines the question points to. Underline or note the words that matter, such as a contrast word or a key noun.
Predict before you look: Say a short answer in your own words, for example: the author is saying the lakes are shrinking faster than expected. Don't worry if the wording is rough.
Eliminate with evidence: Go through the choices. For each, ask whether the text supports it. Cross out any choice the lines don't support, even if it is true in the real world.
Choose the closest match: Pick the remaining choice that best fits your prediction and the evidence. If two are still close, reread only the key lines and decide which one the lines support more directly.
Worked example: working one short passage and its question
Here is a short passage written for this article, followed by a question of the kind you will see.
Passage: Ravi counted the birds at the pond every Saturday for a year. In spring the count rose quickly, from 12 birds in March to 40 in May. By August it had fallen back to 15. Ravi concluded that the pond was most useful to birds during the spring months, when it provided food and nesting space.
Question: Which choice best states the main conclusion Ravi draws from the counts?
Step 1: The question asks for a conclusion, so the answer is a claim about the whole passage, not one detail.
Step 2: The key lines are the last sentence, which states Ravi's conclusion, and the counts that support it.
Step 3: Prediction: the pond is most useful to birds in spring, because the count peaks then.
Step 4: Eliminate. A choice that says birds are most numerous in August is contradicted by the August count of 15. A choice that says Ravi counted birds for only one season is contradicted by the year-long count. A choice that says the pond supports birds in spring matches the text.
Step 5: Choose the spring-support choice, because it matches the prediction and the last sentence.
Check the numbers in the passage as you go. The count rose from 12 to 40 between March and May, an increase of 40 − 12 = 28 birds. It fell from 40 in May to 15 in August, a drop of 40 − 15 = 25 birds. Both changes are real in the text, so a choice that says the count was steady all year would be wrong on the numbers alone.
Notice what you did not need. You didn't need outside knowledge about ponds. Every correct elimination pointed back to a line in the passage.
Handling grammar questions the same way
Writing questions follow the same logic with a different kind of evidence. The sentence is the evidence. Before you look at the choices, decide what the sentence needs: a full stop between two complete ideas, a verb that agrees with its subject, or a transition that shows the relationship between two sentences.
If you can't name the rule, read each choice aloud in the sentence. The one that sounds complete and logical is usually the one that follows the rule, but check it against the rule before you commit.
Mistakes to avoid
Reading the whole passage slowly before you look at the question. You will forget the details you need.
Choosing an answer because it is true in general. The test asks what the passage supports.
Skipping the prediction step. Without a prediction, the choices all start to sound right.
Changing an answer without a new piece of evidence. Change it only when you find a line that proves your first choice wrong.
Your plan for this week
Take one set of Reading and Writing questions from official practice materials, reading each question before its passage.
For each question, write the prediction in one line before you look at the choices.
Log every question you got wrong, with the line of evidence that proved the right choice.
Redo the wrong questions from the log a day later, without looking at your first answers.
After a week of this, you will notice that most of your errors come from one of two places: predicting too late, or eliminating by feel instead of by line. Both are fixable, and both are much easier to see in a log than in memory.
Frequently asked questions
Should I always read the question before the passage?
For most practice, yes. It tells you what evidence to look for. Some students prefer to skim the passage first, so try both and keep the one that gives you fewer wrong answers.
What if two choices both seem supported?
Reread only the key lines. The better answer usually matches the lines more directly, and the other is either a little too strong or a little too weak.
Do I need to memorize grammar rules first?
Learn the common ones, such as sentence boundaries and agreement, because they come up repeatedly. Then use the evidence-first habit on every question.
