After the NEET UG exam, students look forward to prepare for AIIMS or JIPMER (MBBS) exams. There is a slight difference in the preparation approach for AIIMS, JIPMER, and NEET. AIIMS is much more difficult to crack than NEET because of the limited number of seats and difficulty level of questions. You need to solve JIPMER questions in less time than the NEET questions.
The structure of NEET, AIIMS and JIPMER is given below:
An outline of the major differences between the exam preparation approaches required for AIIMS, JIPMER and NEET exam is given below:
Example question from AIIMS:
Directions: In the following question, two statements are given. One is assertion and the other is reason. Examine the statements carefully and mark the correct answer according to the instructions given below.
Assertion: Reproductive isolation brings about sympatric speciation.
Reason: It is the primary mode of speciation. e.g. Darwin's finches.
1. Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
2. Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.
3. Assertion is true, but Reason is false.
4. Both Assertion and Reason are false.
Correct Ans. 2
Solution:
Sympatric speciation occurs when a subpopulation that occupies the same niche develops a unique mutation that prevents it from mating with original population. This speciation phenomenon most commonly occurs through polyploidy, in which an offspring or group of offsprings will be produced with twice the normal number of chromosomes. Geographical or allopatric speciation develops when population is geographically isolated.
It has been considered as a primary mode of speciation, e.g. Darwin's finches.
Analysis: It requires in-depth knowledge of the topic to answer the question correctly, since it comes under questions which need thorough understanding. However, in NEET and JIPMER, questions are a bit straight forward.
Example question from JIPMER/ NEET:
Which of the following organelles does not contain RNA?
1. Plasmalemma
2. Ribosome
3. Chromosome
4. Nucleolus
Correct Ans. 1
Solution:
The plasmalemma acts as the interface between the machinery in the interior of the cell and the extracellular fluid (ECF) that bathes all cells. The plasmalemma structure is also termed as fluid mosaic as it is a network of both lipids and proteins. The lipids and proteins are present in varying proportions of 1:1 - 1:3. These lipids are dotted with proteins and are found to stick to the membrane or form a bridge spanning from outside to the inside. It is devoid of ribosome.
Analysis: This is an easy and straight-forward question asked directly from NCERT.
