Here are some of the things that you can do to prepare for these examinations right from the first year onwards. 

• Don’t just mug up the syllabus right before the examination. You won’t remember the things that you read in long term and won’t be able to apply in MCQs.
• Check the previous year’s question papers of the examination that you are targeting. Mark them and practice.
• Understand the examination pattern. In the new pattern, one question requires knowledge of 3-4 subjects. You have to be able to apply basic knowledge of the subjects to solve it.
• Attend dissection and all Physiology and Biochemistry practicals mindfully. This will help in Pathology. 

Be serious about your studies. Plan everything before and go about it at your own pace.
