If you have scored 264 marks in your PCM board subjects and 70 marks in the KCET exam, here is a detailed prediction and explanation of your expected KCET rank:

• KCET Rank Calculation :
  KCET ranking is based on 50 percent of the normalized board marks and 50 percent of the KCET entrance test marks.
  Your PCM board marks are 264 out of 300, which is approximately 88 percent.

• KCET Normalization :
  Your KCET marks are 70 out of 180.
  70 out of 180 is approximately 38.88 percent.

• Predicted Rank Range :
  Considering your strong board performance (88 percent) and a moderate KCET score (38.88 percent), your expected KCET rank can be estimated between 40000 to 60000 approximately.
  Please note that this is a rough estimate and the final rank may vary depending on various factors.

  Difficulty level of the exam
  Normalization process of board and KCET marks

• Admission Possibilities :

  Keep a backup plan like COMEDK or management quota in mind if needed.
