  • by

In this post we are going to discuss about the Biochemistry study tips, Important learning or questions topics and guidance of exam passing preparation with good score.

We are going to discuss about the :

  1. Meaning/Definition
  2. How to read the Subject
  3. What are the important topics
  4. How to perform well in the viva table
  5. How to score well in the University exam

Meaning/ Definition :

  • Biochemistry is the study of the Micromolecules inside the living body.
  • The study of chemical processes within and pertaining to live beings is known as biochemistry or biological chemistry. Biochemistry is a branch of chemistry and biology that is separated into three areas: structural biology, enzymology, and metabolism.

How to read the subject :

“Biochemistry is tough and most irritating subject of 1st year MBBS” – Said by many seniors, friends ??

Hahahahaha 😂😂😂😂😂😂😂

Specially Metabolism part

Now lets come to the truth, at this moment we have just the basic knowledge about Biochemistry.

Still so many research works to be done specially to understand the Metabolism. We know the cycles and some the connections between them, but there are still huge number of connections are present between them. We have to find them.

—Now there are not appropriate and perfect teaching materials are there to make the subject more understandable. So still time is needed to make this subject more easy and conceptual.

—And thats why so many research works are ongoing at this moment.

Conceptual Study :

To understand metabolism try to connect it with your real life. How you are consuming foods and they are becoming energy, stored materials and something else.

Like if you are taking Protein : Then you are not getting energy quickly, because it takes time to burn calories from protein

If you are taking Carbohydrates : Then within few minutes you are feeling energised. So from here you can understand why Glycolysis occurs inside of our body. Cool na??😎

Yes that much cool is Biochemistry, just you have to think by yourself, think and think

How to perform well in viva table :

Now for performing better in Viva table you must have to go through important topics and as well as other topics of your syllabus.

Make a small notebook, start making every chapter short within 5-10 pages, so in one notebook you will be ending all the chapters of Biochemistry.

For basic questions just make sure you have done all the Lecture classes provided by your Institution. Those topics are enough for passing marks.

But if you are aiming for better score like 80%, then make sure that you have knowledge about other topics also.

And make a quick revision of all of them one night before the Viva. And don’t try to be over smart in the viva table. Try to answer what the examiner is asking to you. He/She is so much experienced and can easily catch your over smartness which will not be healthy for your marks. So from that point we can say that ‘your appearance’ also does matter.

How to score well in the University exam :

Solve previous 10 years paper of your University, from there you are going to get 70-80% questions common, rest other questions can be asked from whole book.

If your university has semester system, then try to solve that year’s all colleges semester papers under that University. From those questions you can get rest 20-30% uncommon questions.

Presentation :

Now how to write the exam paper ? . For each question, a image carries separate marks, so try to put images/flowcharts in each answer. So the examiner can easily smell what you have written or what do you know about the topic. If the flowchart is clearing everything then it will be your time and don’t forget to Highlight key points of your answer. In written part also try to write answers to the point manner, not write everything in one paragraph.

Now if you have done all these things then the impressed examiner will not hesitate to put 75-80% marks.

So each question should contain a clear diagram/flowchart, Highlighted key points, and to the point answers.
