GRE® General Test Overview



What Is It?

The GRE® General Test measures verbal reasoning, quantitative reasoning, critical thinking, and analytical writing skills that are not related to any specific field of study.


Verbal Reasoning — The skills measured include the test taker's ability to

•analyze and evaluate written material and synthesize information obtained from it
•analyze relationships among component parts of sentences
•recognize relationships between words and concepts


Quantitative Reasoning — The skills measured include the test taker's ability to

•understand basic concepts of arithmetic, algebra, geometry, and data analysis
•reason quantitatively
•solve problems in a quantitative setting


Analytical Writing — The skills measured include the test taker's ability to

•articulate complex ideas clearly and effectively
•examine claims and accompanying evidence
•support ideas with relevant reasons and examples
•sustain a well-focused, coherent discussion
•control the elements of standard written English

Who Takes It and Why?
Prospective graduate applicants take the General Test. GRE® test scores are used by admissions or fellowship panels to supplement undergraduate records and other qualifications for graduate study. The scores provide common measures for comparing the qualifications of applicants and aid in evaluating grades and recommendations.


Where Do People Take It?
The General Test is offered year-round at computer-based test centers in the U.S., Canada, and many other countries. It is offered at paper-based test centers in areas of the world where computer-based testing is not available. See which format is available in your area.

Who Accepts It?
Any graduate, business or professional school, or any department or division within a school, may require or recommend that its applicants take the General Test, a Subject Test, or both. If approved by the GRE® Board, an institution seeking accreditation can also receive test takers' scores.

Computer-based General Test Content and Structure

The computer-based General Test is composed of Verbal Reasoning, Quantitative Reasoning and Analytical Writing sections. In addition, one unidentified unscored section may be included, and this section can appear in any position in the test after the Analytical Writing Section. Questions in the unscored section are being tested for possible use in future tests, and answers will not count toward your scores.

Total testing time is up to three hours, not including the research section. The directions at the beginning of each section specify the total number of questions in the section and the time allowed for the section.

The Analytical Writing section is always first. For the Issue task, two topics will be presented and you will choose one. The Argument task does not present a choice of topics; instead, one topic will be presented.

The Verbal and Quantitative sections may appear in any order, including an unidentified unscored section. Treat each section presented during your test as if it counts.

Typical Computer-based GRE® General Test

Section

    Number of Questions

Time

    Analytical Writing         1 Issue Task*   45 minutes
    Analytical Writing         1 Argument Task*   30 minutes
    Verbal          30   30 minutes
   Quantitative          28   45 minutes
   Unscored**         Varies  Varies
   Research***                   Varies                         Varies

* For the Issue task, two essay topics are presented and you choose one. The Argument task does not present a choice of topics; instead one topic is presented.
** An unidentified unscored section may be included and may appear in any order after the Analytical Writing section. It is not counted as part of your score.
*** An identified research section that is not scored may be included, and it is always at the end of the test.


Scores:

*There are three different portions of the GRE test, and three different scores.

*The essay portion is scored on a scale of   -  0 to 6, in half point increments. 

*The verbal & quantitative reasoning portions are scored on a scale of - 200 to 800, in 10 point increments.

*There is no passing or failing cutoff, but the higher your score the better your chances of getting into the program you're considering.

SQL - Structured Query Language


what is SQL?

SQL (Structured Query Language) is a database computer language designed for the retrieval and management of data in relational database management systems (RDBMS), database schema creation and modification, and database object access control management.

SQL is a querying language for querying and modifying data and managing databases. SQL was standardized first by the ANSI and later by the ISO. Most database management systems implement a majority of one of these standards and add their proprietary extensions. SQL allows the retrieval, insertion, updating, and deletion of data.

OR

Structured Query Language (SQL) is a specialized language for updating, deleting, and requesting information from databases. SQL is an ANSI and ISO standard, and is the de facto standard database query language. A variety of established database products support SQL, including products from Oracle and Microsoft SQL Server. It is widely used in both industry and academia, often for enormous, complex databases.

 

In a distributed database system, a program often referred to as the database's "back end" runs constantly on a server, interpreting data files on the server as a standard relational database. Programs on client computers allow users to manipulate that data, using tables, columns, rows, and fields. To do this, client programs send SQL statements to the server. The server then processes these statements and returns replies to the client program.

RPC - Remote Procedure Call



What is RPC?

Remote Procedure Call (RPC) is a protocol that one program can use to request a service from a program located in another computer in a network without having to understand network details. (A procedure call is also sometimes known as a function call or a subroutine call.) RPC uses the client/server model. The requesting program is a client and the service-providing program is the server. Like a regular or local procedure call, an RPC is a synchronous operation requiring the requesting program to be suspended until the results of the remote procedure are returned. However, the use of lightweight processes or threads that share the same address space allows multiple RPCs to be performed concurrently.

Mothers Day Wishes



"We only have One Mom, One Mommy,
One Mother in this World, One life.
Don't wait for the Tomorrow's
to tell Mom, you love her"

************************************************

"To the world you might just be one person,
but to one person you might just be the world."

************************************************

A PRECIOUS MOTHER

Mom You've given me so much,
Love from your heart
and the warmth of your touch.

The gift of life and you're a friend to me.
We have a very Special Bond
which only comes from God...
I'm sure you agree.

As a child I would say Mommy I Love You,
Now you're my Mother so dear
I love you even more
with each and every new year.

If I could had chosen,
I would have picked no other.
Than for you...to be my lifelong friend
and Precious Mother.

************************************************

AS I LOOK BACK...

As I look back on my life
I find myself wondering...
Did I remember to thank you
for all that you have done for me?

For all of the times you were by my side
to help me celebrate my successes
and accept my defeats?

Or for teaching me the value of hard work,
good judgement, courage, and honesty?

I wonder if I've ever thanked you
for the simple things...
The laughter, smiles, and quiet times we've shared?

If I have forgotten to express my gratitude
For any of these things,
I am thanking you now...
and I am hoping that you've known all along,
how very much you are loved and appreciated.

************************************************
