Learning takes effort, time and dedication. All three have their roles in driving you to learn. Check yourself with existing knowledge in the domain and then see how much someone with expertise knows. Catch up with the learning pace to remain relevant in the competition. Below are some of the points that you must bring:

Set Clear Goals

To speed up your learning you need to have clearer goals. The goals will make your vision clearer. Try to make it more practical and realistic. For example, if you want to cover the syllabus in a specific time period then devote more time to complex topics. Chart out short-term and long-term goals.
 

Activate Prior Knowledge

You must have prior basic knowledge related to the topic. That basic conceptual knowledge will help you to understand advanced concepts. When you are approaching complex concepts then you need to have prior basic knowledge so that you can have it derived from the first principle or make out the conceptual linkages.
    

Chunking Technique

Break down complex problems in small chunks. Master each concept before moving to other concepts. Building a strong knowledge base is very important. Work on comprehensive details and retention. Be more focused and concentrated on your work.
 

Employ Spaced Repetition

Rote learning is an illusion that will weaken our conceptual understanding ability. Tools such as flashcard apps or spaced repetition software help you schedule and optimize your review sessions.  Spaced repetition from well-organized notes will help you more.
 

Take Breaks and Rest

Overloading concepts will not make you master the concepts. Taking regular breaks will refresh your mind. Schedule short breaks to relax and recharge your mind. Scientific studies have shown that regular breaks improve productivity. This will allow your brain to process and consolidate concepts.

Emphasize Quality over Quantity

The time you spend learning deeply and analytically. Build your understanding around underlying principles and apply critical thinking. Check how deep you need to go. Unnecessary accumulating too much knowledge is also not required.

Take Test

Take the Mock test after covering 4 to 5 chapters. That will show you how much knowledge gap you have. Then strategies to work on those concepts. Analyse each mock thoroughly and note down the concepts in a separate note. When I was studying at CEPT University (also known as Centre for Environmental Planning and Technology), I tested this strategy and it finessed my skills of Mathematical Ability in Construction Technology. The more you practice precisely based on your conceptual gaps the more you will improve.
