After cracking neet,if I get a low quality government college based on my marks,can I be a good doctor?

Moni, your NEET marks determine which Medical College you get a seat in. The rest 5 years depend on how hard you work. Most MBBS graduates learn through the Clibical postings and practical exposure. You might not remember Brachial plexus when you read it but when you dissect it in the Anatomy lab you get a practical exposure and when you treat people with radial, ulnar and median nerve injuries, you gain knowledge and confidence. This is how you become good at anything in life. So do not worry about whether you will become a good doctor or not. Focus on scoring good marks and secure a MBBS seat. Rest all will fall in place.
