Hello there,

Here are the details regarding your query:

• As long as you're currently enrolled in the BTech program, your admission won't be canceled due to your HSC percentage.
  
  

• Regarding the improvement exam, it depends on your college's policy. Most colleges allow students to improve their marks in specific subjects through the Maharashtra board's improvement exam. You should check with your college's administration or the Maharashtra Board for the specific guidelines and eligibility.
  
  

• Keep in mind that achieving the required 60% or more in the improvement exam will make you eligible for placements, if that's your concern.
