To determine your chances of getting a government college through KCET, let's look at the KCET rank calculation and previous year's cutoff trends.

KCET rank is calculated based on both KCET scores and PU (PU PCM aggregate) scores. The rank formula is:

KCET Rank = (300 - KCET PCM aggregate) + (300 - PU PCM aggregate)

With your KCET rank being 166563, it's challenging to predict your chances without knowing the specific cutoff trends for the current year and the colleges you're interested in.

However, here are some general steps you can take:

1. Check the official KEAM counseling website for updates on seat allocation and counseling schedules.

2. Look up previous year's cutoff ranks for government colleges in Karnataka.

3. Consider factors like category (General, OBC, SC/ST, etc.) and region-specific colleges.

If you'd like more specific guidance or help with calculating your chances, please provide:

1. Your KCET score

2. Your PU PCM aggregate score

3. Your category (if applicable)

This will help me provide a more tailored response.
