Dear aspirant, first of all be calm. I can tell you from my experience that even I was skeptical while I was preparing for NEET but I never let my overthinking and negative energy hamper my studies and well the results were satisfying , I’m a medical student now.
So, my advice to you is to remain calm as much as you can. I know it’s easier said than done but you are your best friend at the moment and you need to do it for yourself. Be diligent and focus entirely on your studies, don’t worry about the results. If you are true to your preparations (of which I’m damn sure you are ) no one can stop you from achieving your goal. Be a cheerleader to yourself, motivate yourself, make yourself realise your worth and stick to your path.
Have faith in your preparations and prepare till you enter the exam hall for NEET and I’m sure you will be successful. Try not to overthink at this moment and continue with your journey. Instead make your studying schedule a little busier than before to not let your mind wander here and there and never forget to rejuvenate yourself from time to time.
My best wishes are with you.
All the best for the exam!!
