The first-year science admission subjects and options will vary depending on the specific university or college you are applying to.

• Physics: This subject is mandatory for most science programs.
• Chemistry: Another mandatory subject for science students.
• Biology: Essential for students pursuing a Biology (PCB) stream.
• English: Often mandatory to develop strong communication skills.
  
  
  
  
• Optional Subjects (Options May Vary):
  • Mathematics: A common option, but not mandatory for a PCB stream in some colleges.
    
    
  • Psychology: This might be offered as an optional subject in some colleges, particularly those with strong social science departments. However, it's less common than Mathematics.
    
    
  • Computer Science: An increasingly popular option for science students as it equips them with valuable technical skills.
    
    
  • Environmental Science: This subject is becoming increasingly relevant and might be offered as an option.
    
    
  • Informatics Practices: Introduces students to computer fundamentals and can be a good alternative to traditional Mathematics.
    
    Yes, in some colleges, you might be able to pursue a PCB stream without taking Mathematics in the first year. However, this option is not universally available.
