Hello!We are here to guide you don't be sad like the emoji in your question.

I wonder why y want to get exactly 135-140.Its okay to set a target but you didn't mention the stream you are interested in  getting into.

->for 140 marks your rank will be around 23k 

->computer science engineering-25k(open) & 49(closing)

->electrical engineering- 27k to 76k

->chemical engineering - 9k to 21k

-> information technology- 74k to 1L

So on..

 You can check all the cut off ranks In NIT srinagar official website.

HERE IS THE BEST STRATEGY That I can suggest you

-> make a schedule every day time table that how many hours you have to study per day

-> spend 4hrs a day for preparation from now

-> say no to enjoyment every day take one day break for every week

->complete the syllabus within the time table you have made

->maintain a separate book in which you write all the formulas,Note points of all the subjects

-> revise the book and write the mock tests atleast couple of tests in a week at the last month of preparation

Hope this is helpful.Feel free to ask any questions.

GOOD LUCK for your Exam!

Hard work is the key of success . But this is the era of doing smart work . You should solve previous years questions . Apply for the TestSeries . This would help you a lot . Focus on important topics which are scoring as well . And there are lots of video lectures availabe on YouTube . So if you have doubt in any topic then you can watch them for free .

Have a balanced diet , Sound sleep . 

All the best !!!

You still have time to prepare and I think you should keep a target of at least 40-50 more marks then you think you want.
