Its March again, the time of the year when students gear up for the board exams. Students may be burdened with questions such as How to master a subject? How to revise for the exams?
Apparently, to their dismay they may realize that they cannot apply the same learning strategies to all the subjects. For example, the theories of physics need to be tackled differently to those of the processes of biology.
Biology is a subject of life and lifeforms, so try to build genuine interest in it. Here are a few tips on how to master this subject:
Unit | Topic | Marks |
1 | Reproduction | 14 |
2 | Genetics and Evolution | 18 |
3 | Biology and Human Welfare | 14 |
4 | Biotechnology and its application | 10 |
5 | Ecology and Environment | 14 |
- Practice the crosses related to Mendelian genetics thoroughly.
- One can make short flow charts or tables in order to remember these crosses.
- Given below is a table representing the genotypic and phenotypic ratios of the crosses involved in Mendelian genetics
Cross | Phenotypic Ratio | Genotypic Ratio |
Monohybrid Cross | 3:1 | 1:2:1 |
Dihybrid Cross | 9:3:3:1 | 4:2:2:2:2:1:1:1:1 |
Incomplete Dominance | 1:2:1 | 1:2:1 |
- Study the processes related to molecular biology (such as DNA replication, transcription and translation) very well. Prepare pointers for these processes.
- Split the technical terms, etymologically for better understanding. For Example: in order to remember the term karyokinesis, split it into karyo (meaning nucleus) and kinesis (meaning synthesis).
- These pointers work for the rest of the units as well. Try to make mind maps and flow charts for the processes involved in biotechnology.
- Clear any doubt related to any topic immediately from your mentor, teacher, tutor or friend. Else post your doubts on ‘Ask and Answer’ on meritnation.com and get expert help. Remember “Expert help is just a click away”.
How to Revise
For example: The question on the structure of antibody has been asked in 2009, 2010 and 2011 in the papers of the Delhi region. The way in which the question was asked was different but the answer is almost similar.
The questions were:
(i) What does the above diagram illustrate?
(ii) Name the parts labelled ‘a’ and ‘b’.
(iii) Name the type of cells that produce this molecule.
2010 (Set 3) – 3 marks
An antibody molecule is represented as H2L2. Explain.
2010 (Set 3) – 3 marks
Identify A, D, E and F in the diagram of an antibody molecule given below.
During the Examination
All the Best
