Interleaving is a technique where you mix up things as you study. For instance, while studying about Patent Specification, you mix up relevant portions of the Act with the details about Patent Specification that appear in different parts of the rules. When you do this, you not only learn about the parts pertaining to Patent Specification in the Act but also the details like margin space, form used etc from the Rules. Sections 9 and 10 deal with provisional and complete specifications but the details are spread across different provisions of the Rules. So when you look at rule 13, you will get the details of what should get into a specification.
You need not just stop there. You can also look at the form by which a specification is filed, the variable fees paid for specifications depending on the number of pages and the number of claims it contains, etc. What you would do in a normal case is just look at sections 9 and 10 and move forward but interleaving would require you to mix up things pertaining to the specification which may be directly or indirectly relevant to the study topic.
The general tendency while preparing for competitive examinations is to study parts of the syllabus and gain proficiency in that particular topic. This is called blocked practice. Blocked practice is boring and does not bring the benefits of interleaving practice.
So what you should do is to get a preliminary understanding of a topic and quickly move to the details about the topic which may be appearing in different parts of the Act or the Rules. By doing this you may undergo some difficulty as you may be jumping from one topic to another, but it will give you exposure to different learning impediments overcoming which will help you to strengthen your knowledge.
Interleaving is a good way to gain proficiency in your study and that’s the reason we interleave the topics in our Exam Practice Course.
