According to one of my friends at RGUHS, first-year MBBS includes subjects such as anatomy, physiology, and biochemistry. 

• There will be a certain limit to the number of questions asked in the examination. 
• It’s wise to go through previous years’ question papers to have a sound knowledge regarding the pattern and types of reliable questions. 
• Approach your seniors as they will have a stock of “must-read” topics and 10 years of solved question papers. 
• Question banks of Singi Yatriraj are a must-have reference when it comes to solving test papers.
• One simple tip is to read the questions and relate to the important aspects including the condition or phenomena.

Therefore, follow these pointers thoroughly for your exam. By practicing often you will realize that a lot of questions are usually repeated.
