Just focus on a single thing dear, multiple vows will result into nothing. If you are scared of faliure then don’t come into the field, even a minor mistake of a surgeon will not only cost the life of the patient but also can cause his misfortune as in India ,we all know how doctors are treated in the government sectors.
I will firmly suggest you to leave Bsc and focus solely on Neet and start prepare accordingly to it.
What will happen , if I fail to grab a seat next year ?
A warrior never fear of his death, he just fight till the last blood.If you think you are not a warrior , then go and start doing other things.And some people will call “ beti to Shaadi ki Umar ki ho gayi he , ab BHI preparation chal Raha hai ?”
Believe me mate, after you crack the neet exam , they will come to you and say “ beta hmare ko mukt me darshan dena ha 😂”
Pain is temporary but achievement is permanent. No need to put your ass on fire , just follow the basic routine and stick to it wisely.Neet / jee need only maturity not big brain and maturity only comes by practice and temperament not the age
