How to find logical errors in GMAT essay questions

Common logical errors in GMAT essays mainly include no causal connection, insufficient sample, false analogy (horizontal), time-place congruence, failure to look at the problem from a developmental point of view, either/or, questionable investigations, and unfounded assumptions with conclusions. Each logic error has its own distinctive characteristics, and as long as you accurately grasp its characteristics, you can quickly and accurately lock it down during the exam. The GMAT consultation on the official website is more comprehensive, and it also talks about no causal connection, which means that the explanation given by the author and the conclusion reached are not causally connected, or the two are not related.

Insufficient sample means that the arguments or examples given are insufficient to illustrate an issue and not support the author's conclusion. False analogies are comparisons between two unrelated things and some conclusions can be drawn from them. Temporal and local congruence mainly refers to the failure to look at problems from a development perspective, to compare past examples with the present, and to draw conclusions from them.

Choosing one or the other limits the scope of the conclusion and draws conclusions from an either/or perspective. Suspicious investigation refers to the fact that the evidence provided by the author is one-sided or limited, and does not guarantee the smooth conclusion of the conclusion. An unfounded conclusion means that the conclusion reached is unfounded, or that the previous assumptions are untenable.

These two areas do not count towards the overall score, but some schools will require scores for both components.

AWA is easier to review and easy to get a decent score. The words of the review advice are as follows:

The original questions of the argument are all logical, and he just lacks details in many links to bluff people. If you can't see his jumping logic for a long time, it will definitely be difficult to grasp the main point, and the writing logic is not clear, and the speed will naturally be slow.

I suggest: take a look at the classic AWA Seven Deadly Sins. There are many classic logical errors in the Seven Deadly Sins, and the scope of the AWA question probably will not exceed these seven deadly sins.

Read more sample essays. Those who can do model essays are those who can see logical loopholes and have a good language organization. It's worth learning.

The essence of writing: the language is simple and clear, and the expression is formal and effective. The language does not need to be flashy.

Practice writing according to the template and revise it according to the sample text.

If you review IR, few people conclude that the strategy is because the types of questions in IR are too complex, the question types are diverse, there are few rules, and there are a lot of questions, but the questions in the exam room are still different from what we do. So if you have the effort, let's get verbal and quantitative done first

In the GMAT test, although the essay and IR are not counted in the overall score, they should not be taken lightly, because some schools will require scores in these two parts, so you still have to take it seriously! Generally speaking, getting 4+ in composition and 6+ in IR is relatively good, and it is enough to apply to schools. The specific situation depends on the requirements of the institution you are applying to.

It would be better to give a choice to the PS question!

Topic: A shop sells newspapers, A reports 1 knife per copy, B reports each copy of the knife. There were no other newspapers to sell that day. If r% of the store's total revenue comes from the sales of newspaper A, newspaper B accounts for p% of sales, and P is used to represent R.

Solution: Let's buy a total of x number of newspapers.

From the title: A sales volume (100%-p%)x, B sales p% xr% = A total profit divided by (A + B) total profit.

r%=1*(100%-p%)x (1*(100%-p%)x+Propose x approximation, and then simplify it.

Finally, r%=(100%-p%) 100%+
