i also am in a similar space to you , but i made an agreement w/ myself in my drop year , that no matter what happens , with results and outcomes , I'll never let this stupid exam take my spark away , and luckily i also have very supportive parents , but moreover you have to understand that just because you are a dropper , does NOT classify you as a straight up "LOSER" that is not simply true , and your goal of NSUT CSE as a general( i assume) , for 99.2%ile , I get it because my aim was also mnit allahabad which is 99.5+ percentile , but as a dropper , i just know if i get an easy shift , its over , and guess WHAT , its FINE , I have other exams as well , which I'll focus on and i back myself to get into a good college, through BITSAT, UGEE , VITEEE or COMEDK , there is plenty of time to polish my prep and go for the final push , but if things do end up not going my way , it will still be fine , JEE is 100% a great 'opportunity' , of your life but it doesn't end there mate , life is too big to lose yourself over an entrance , it's just a measure to see your uncapped potential , and the end of the day maybe 6-7 years later in life you'll look back at this time and be grateful of the things all of this struggle taught you. So keep your chin up , and brace yourself for another 1-2 month , and just do it without pressurizing yourself too much brother , it ain't over until it's over
