MCAT Examination is characterized by the following:

• it is held twice a year in April and August. The test is conducted in 40 different versions on the test date for exam safety purposes.
• It has 4 parts: Verbal Reasoning, Problems from Physical Sciences, Writing Samples and Biological Problems including Organic Chemistry.
• Special student manual can give sample questions of MCAT exam and other supplementary exams information;
• Except the Writing sample section, each section of MCAT is given a score ranging from 1 to 15. It is possible but not advisable to re-pass the MCAT. The reason being, both your performances will be taken for consideration after taking the average of the two.
• MCAT will basically test the knowledge in medical area. MCAT will not test your Mathematics knowledge.
• Although MCAT is conducted twice a year, better give the test when you feel well prepared. Beginning from 2007 there will appear Computer Based Test.

Physical Sciences
This section includes physics and general chemistry. The biological sciences test covers biology and organic chemistry, with an accent on biology.

The MCAT science portions comprise a series of passages, containing several questions or problems. Often the passages involve unfamiliar situations and, rather than numbers, explanations, relationships among various quantities, and extrapolations to new situations. There is no ordering from easy to difficult. The pre med students find it quite difficult to get prepared fort the test and get irritated and scared of the coming exam.The only way to prepare for the tests is to learn a lot of physics, math and biology.

The MCAT lasts for more than 6 hours and consists of 4 sections:
- Verbal Reasoning,
- Physical Sciences,
- Biological Sciences,
- Writing Sample.

You must possess at least general items to hope to pass the test. In your studies, you should concentrate on the ideas underlying the knowledge. Only most simple equations are used so you need not learn them directly for the exam. The purpose of the MCAT is measure how well you reason, not how much knowledge you have. 

Except for measuring your reasoning ability, the MCAT is testing your problem solving skills.
You need to develop special problem solving approach to find better solutions. Then you can solve future MCAT problems by thinking in the same way as when you solved previous problems. 

It is important that even in scientific passages you preserve visualization capacity. It will help you understand what gist of the problem. In physics it is an ability to see electrons, in biology – organelles. If you view science as a mere collection of facts and equations to memorize, you will find it frustrating. On the contrary, if you approach science looking for new concepts, themes and a new worldview, then your efforts will be justified. 
verbal reasoning

The reading comprehension portion of the MCAT is 85 minutes long and consists of about 9 passages, each about 500 words long and each with about 7 questions. Politics, history, culture, and science are the most common themes in the test.

Most people find the passages difficult because of the unknown subject matter content.  Obscure subject matter is chosen so that your reading comprehension will be tested, not your knowledge of a particular subject. Also the more latent the subject the more likely everyone taking the MCAT will have the equal opportunities.

But as the target audience consisting mostly of laymen, the test doesn’t comprise extracts from abstract math or philosophy. In fact, if you read books on current affairs and the Op/Ed page of the newspaper, then the style of writing used in the MCAT passages will be familiar and you probably won't find the reading comprehension section particularly difficult. 

The extracts are accessible for the majority of people. Usually the chosen article is heavily. The formal style of an extract is retained but much of the "fluff" is removed. As the original article is contracted much, the MCAT passage contains 3 times more info preserving the same length. This is why the passages are similar to the writing on the Op/Ed page of a newspaper. After all, a person writing a piece for the Op/Ed page must express all his ideas in about 500 words, and he must use a formal (grammatical) style to convince people that he is well educated. Extracts and passages can be untitled; they can begin in the middle of an explanation. They are dry and unfamiliar.
