I especially have trouble with lab techniques ( i always hated lab).virilep said:I think everyone has trouble with Ochem. Trick is to just keep doing practice passages. they can only ask u the laws of acid base hydrogenation so many ways!. and the SN2 stuff. all you gotta do is memorize the laws and keep working problems (and making sure to see why u got them wrong). I never really studied Ochem as much as I did bio and physics. but you can do it!!!
Beginning with the 2003 MCAT administrations the broad structure of the MCAT was maintained, but with the following changes:
Three questions on DNA and genetics were added to the Biological Sciences section. In the biology portion of Biological Sciences, one new topic, "Molecular Biology: Eukaryotes," has been added. Note that this topic falls within the content typically covered in undergraduate introductory science courses. The three additional DNA and genetics questions are included under the topics, "Molecular Biology: Eukaryotes" and "Molecular Biology: DNA and Protein Synthesis."
In the organic chemistry portion of Biological Sciences, the topics, "Oxygen Containing Compounds" and "Hydrocarbons" are reduced by a total of three questions. Under the topics, "Hydrocarbons" and "Oxygen Containing Compounds," sub topics Alkenes, Benzene, Phenols, and Ethers were deleted. Some questions may, however, refer to these sub topics. In such cases, relevant information on these sub topics will be provided.
To ease time pressure, the Verbal Reasoning section is reduced by five questions. The total number of test passages remains the same, with the reduction occurring within some of the passages on the test. The time limit remains unchanged. The administration order is reversed for the Verbal Reasoning and Physical Sciences sections, so that Physical Sciences is the first section of the morning.
Scores of 14 and 15 on Verbal Reasoning are re-instituted (replacing the current top score of "13-15".) A "Total" is reported for the multiple-choice sections (Verbal Reasoning + Biological Sciences + Physical Sciences) conjoined with the Writing Sample score, e.g., 42T, in addition to the individual section scores.
