    1. Hey, I don't remember those things now. It's been a year. How do you expect me to remember those formulas ?
      They were just for JEE purposes.

  2. bhaiya, i sat for nsep 2013 but couldn't qualify. My concepts are clear but the type of problems they give are somewhat directly formulae based or direct results of questions from hcv and irodov. Could you give me some tips regarding this problem

    1. Maybe because of poor examination temperament, your exam went bad.
      You should think about the following :
      Which questions went wrong ?
      Why did they go wrong ?
      Did you commit silly mistakes ?
      Did you make conceptual errors ?
      Did you go blank ?
      Did you leave a number of questions ?
      Were you able to solve subjective problems ?

      The answer to these questions will help you to judge yourself

    2. from where can I get some sample papers (except the previous year papers ) sothat i can practice

      Delete
    3. Buy fiitjee papers. Or maybe resonance/bansal/narayana test series.
      All are good but be warned that FIITJEE material is the toughest and sometimes it is irrelevant

  4. bhaiya i am getting 1450 rank in AIITS .is it going to help me in getting in top 500 rank?how to improve in AIITS as the questions are quite tough?

    ReplyDelete
    Replies
    1. AITS is not JEE.
      I agree that AITS questions are extremely tough but you should still try to work them out because the people ahead of you in AITS are going to be your competitors in JEE

  5. Bhaiya, how did you manage space in the exam as the rough space is less and if solutions require more calculation what should be done to utilize space .One more thing ,what does nsep actually test ,memory ,concepts or both

    ReplyDelete
    Replies
    1. For nsep : check past year papers.
      For rough space : manage it yourself. You are preparing for JEE. You should be smart enough to handle everything yourself

  8. Can you please answer some questions regarding your strategy towards physics :-
    1)Did u use to read the chapter beforehand which was to be taught in your coaching?if yes,then from hc verma/halliday resnick or any other source?
    2)What order did you use to follow at home for studying once a chapter was started in your coaching?if u had read the chapter beforehnd,then did you read the chapter again at home?how did you go solving questions(conceptual+numericals)??Did you first solve questions from hc verma or fiitjee pckge or dc pandey?
    3) I personally find fiitjee's physics package to be tough?Did you also find it to be tough?

    1. See, my physics teacher was just too awesome. So, I never needed a book for physics. His notes were sufficient. And he made us practice high level question that greatly improved my fundamentals.
      So, I just had to revise his notes and physics was done.
      I used to (sometimes) read ncert/hc verma before hand. I just went through the headings to see what was to be done.
      I never found fiitjee packages to be tough because tougher things were already done in class. My teacher used to make us solve olympiad and irodov questions in class and we enjoyed his class.
      Never faced any major problem in physics

  9. i've solved the entire HC VERMA MECHANICS + (dc pandey MECHANICS (except subjective)).... do i really need to do irodov MECHANICS...! is it that necessary... can u tell the difference between IRODOV AND DC PANDEY....... (like PANDEY IS ____ % OF IRODOV)///.

    ReplyDelete
    Replies
    1. No. It's not at all necessary if you are confident enough.
      Just try 4-5 problems of irodov from a particular chapter. If you are able to do them then congrats! you have understood the topic well. You may now choose to leave other part (not recommended although).

      PS : Please don't insult irodov by comparing it with DC Pandey. Irodov is much better than DC Pandey

  10. Sir i really want to get in IIT B and opt CSE GEN ctg. i just have an year left ( i am dropping) i had coaching but never paid attention. Now i can even kill a planet with Gas war.jk. this year i am not opting for coaching no money mate. So i was wondering if u could tell me about some study material and guidance. That'd be Great. Massive Thanks.plus i was wondering to go with MIT opencourse lectures. How that'd be ?

  16. The portion " Statics & Dynamics " :-
    1)is it in JEE syllabus & should it be given proper 'individual' attention?
    2)if the answer to the above question is no....from where should i get the concepts of centre of gravity,concept of couples,lami's theorem etc because i don't find them in HCV/Fundamentals of Physics....

  49. Hello bhaiya . Plz help me my physics is weak. My problem is that I don't understand when to consider a ch as complete. I mean I take a lot of time to complete a ch n when I start solving questions I find so many of them that takes too much time to finish n I end up doing a single ch for many days. N I always feel that I have forgotten most of d theory while attempting a ques.
    What did u do ?: complete d theory n then do all its related questions in a single go or do it in parts (I start forgetting theory when I solve in parts) I don't feel satisfied usually

  83. Hey, I have searched did places but was not able to find a proper formula for slope of a 3 dimensional figure because that can make vectors really easy in some parts, I'll be really thankful if you could help with it. Also another query, like for calculus in the normal institute book there are 10-15 formulae for differentiation and integration each but in another book there are like 40-50 but many are derived from the simplest forms , so what do you suggest, I should just keep my basics strong and imply on questions or learn all those derived formulae and answer the question in like one two step which can be much much more stressful and time consuming.
