KEAM normalizes both the entrance exam score (out of 600) and Class 12 PCM marks (out of 300) for a combined score of 600. The weightage for each component (entrance exam and Class 12 marks) might vary slightly year-to-year.

The rank is determined by the relative performance of all candidates who took the exam. A higher number of students with similar or higher scores will affect your rank.

Reservation categories have separate cut-offs for admission.

With 155 in KEAM (out of 600) and 244 in PCM (out of 300), your normalized score might be somewhere in the range of 300-350 (assuming a 50:50 weightage for entrance exam and Class 12 marks).

Based on previous years' trends and assuming a score range of 300-350, your rank could be somewhere between 15,000 - 25,000.
