It's 1 month left for my 12th PCM (stateboard Hindi medium)board exam ,and i did'nt study at all...how i get 65% please please

Oh my God... You cannot say didn't study at all at such a critical time of your life.. I feel bad for your parents and for you to be very honest. But leaving these things aside, and giving you the tips so that you can give your level best in the exam, I suggest you to solve as many as exercise mathematics problems. Questions come ditto from exercise. So now as it is late, don't go for completing all the chapters, do as many as you can.. Probability, Binomial, etc have a high weightage. For Physics, listen carefully, I will suggest you to practice all the theorems and formulas only and SOLVE all the numericals behind the exercise. As honestly if you calculate the marks out of 70, around 45 are for numericals and theorems only. And then if you've time, try to byheart the important important laws and definitions so that you can get some easy marks and can attempt mcqs as well. For chemistry, it's really tough to do the syllabus in the last 1 month. Do as much as you can. Just byheart blindly. Now I cannot tell you much other than this.

Now as it is 1 month and you've already wasted almost a year, so I personally suggest you to not waste any further minute at all, and study day and night, get rid off social media, your friends and mobile everything and just focus on studies and believe me, everything is still possible if you give your best. You still can score 75 and above just stay dedicated towards your work.

Best of luck. Thank you.
