Hello prem,

Hope you are doing well.

As per your question, if you fail in 1st year of agriculture and qualify in neet 2020 then you can do according to situation. Like if you have enough good marks to grab your seats in colleges like AIIMS or government colleges then you can leave your BSC.Like clearing the cutoff is not the only thing because in the medical field there is a lot of competition for grabing their seats in this colleges. So it totally depends on you what you want to do. Honestly as per my opinion if had just qualified or not able to get good colleges for MBBS then you should go on with your BSC degree. As you failed in bsc 1st year not a problem re-exam , work hard and paas this first year, not a big deal.
