I need some serious advice...

Myquals_ BSc in Lifesciences (currently final year) pursuing from a tier-3 college, no internships or work exp but I want to give CAT exam this year and my graduation is in May 2027.So I want some reality check regarding this;

1. I won't have my graduation certificate by the time CAT results will be out I suppose, will it affect my selection in any way?

2. I have a 7/8/9 profile, will I not be considered for selection?

3. I'm choosing to change fields as I realized I am not meant for labs or research and I really like leadership, working in teams..etc Will my BSc Lifesciences background with no Maths since Grade-10 affect in any way.

4. Do I have a chance against all the good profile students out there? Is 6 months of prep good enough to score above 95% percentile?

Please help me out, I really don't know what to do!
