As a child I always dreamt of being a

Hello Gaurika,
First of all i admire your passion that you have the desire to bounce back and proof yourself.Now coming to the basics, if you follow what i have written one thing that i can assure you is a seat in a government medical college with good marks only if you have determination which i think you do and also the caliber to work hard day and night.See to crack neet you must be very good at biology because that is the first step towards crcaking the toughest exam. It carries more marks and is easier to remember. But easy as said than done you have to make sure you revise all the chapter of biology and do enough mcqs. Mcqs are the only way out. You have to keep doing mcqs and make sure you dont repeat same mistakes again. Make a separate note for the difficult ones and see them once every day. Biology is nothing but memory and the more you practice mcqs it will be easier to remember.Next comes chemistry. Chemistry is quite similar to biology as it requires alot of things to be remembered by heart specially chapters from inorganic chemistry,periodic table. Organic chemistry is a bit tough but for neet you need not do too many mechanisms and all. General organic chemistry should be learnt and understood by heart. You can make formulae charts and once again do as many mcqs as possible.Now finally physics, the toughest of all. If you are good at maths and physics seems easier then the approach can be different. However most people are afraid of physics and get panicked. However the trick is in mugging up all formulae by heart and knowing the text properly as most questions in neet physics are straight forward from the text. All you need is to clear your concepts know the definitions and practice mcqs. Make formulae charts as most sums are done if you know the formula and more so as they dont give you iit level sums in neet. Practice again and again mug up important mcqs and read the text.Now time management is another important factor. You need to know your weakness and make sure you give more time to that. You need to do your mcqs within time so that you dont lag in the exam. Also you have to give as many mock exams as possible. Aakash and allen provide online and offline test series which are beneficial. So you have to give many exams and give them in time.Practice last 29 years and also refer to some mtg books. Next year cbse wont conduct so stay updated. In the end hard work matters. Also try to avoid facebook,whatsapp,instagram and other social media as they take away concentration. So keep working hard and keep the belief you can. My best wishes for you.
Hope this helps.
