[ In each of these videos there is at-least 1 or more errors. Please tell me about those ]
In youtube if you search as ” Dezrina ” or ” Zookeeper Physics ” you should get to see all the videos.
Thanks and Regards
Zookeeper ;-D Subhashish Chattopadhyay
[ I suggest you see the videos starting with 1- first then starting with 2- ..... in that sequence. ]
[ Tell your friends about this link if you liked the videos ]

In youtube you can search for Dezrina as these have been uploaded with this login-id. or search for ” Zookeeper IIT JEE Physics “
Answers to -> Frequently Asked Questions ( FAQ ) [ commonly asked intelligent Questions :-) ]
1 ) How do I prepare for IIT ?
Ans : – See the videos made by me ( in youtube search as Dezrina or “ Zookeeper Physics “ – will see all ). While watching the videos, take notes and try to solve the problems yourself by pausing the video. Tell me if any calculation is wrong. See the videos with 1- first then 2- and so on. Write to IAPT Kothrud, Pune office to buy ( 150 Rs approx ) the book with previous papers of NSEP ( National Standard Exam in Physics – The 1st level ), INPhO ( Indian National Physics Olympiad – 2nd level ). Prepare with these and see how much you are scoring. You can guess your ALL INDIA rank easily from NSEP, and INPhO rank. Since 1998 the IIT JEE toppers have been mostly representing India in IPhO.
2 ) Some Videos have sound Problem … what do I do ?
Ans : – The room in which the videos have been recorded has windows only on one side. This gives strange echo problems. Also external noise of cars, auto, children shouting have randomly come in. You have to have good speakers with filters or good earphones with filters. We have checked mostly it is OK with these. ( If you are depending only on your embedded speakers of computer /screen / keyboard then there may be extra distortions. As these speakers are often not of good Quality ) In any case reduce the volume see the board, imagine sitting in the last bench and solving the problems of your own. See if your solution differs anywhere with the scribbles on the board.
3 ) Why are you giving these ( high Quality ) lecture for free ?
Ans : Well there are lot of good things free in this world. Linux, My-SQL, Open-Office ….. Go to sourceforge and get thousands of high quality software free along with source code. Yes all officially free …. Why do you think Richard Stallman, Zimmerman, ….. etc are considered Guru philosophers ? In Punjab and Gurudwaras worldwide there are so many Langars where you get better food than Restaurants. … why ? Why do you have Dharmasalas and subsidized rest rooms near hospitals / Famous Temples / various places ? in Iftar party anyone can eat for free … why ? I am teaching for 20 years now and observed most students can do much better if they have the self motivation to solve and practice. Cheap books are available in second hand bookstalls, where you get thousands of Numericals to solve ….. but most students will like to blow their time going and coming for tuition, travel time ….
TV for hours and hours watching cricket / Tennis games, playing computer games …. My free lectures are not going to make much difference in spending of unnecessary money for coaching ….. I know very well , how much people enjoy .. , spending unnecessarily !! Do you know that there are NO poor / needy students in Bangalore. Sometime back I had tried to teach for IIT JEE FREE. Discussed with a few NGOs and social service guys. Arranged rooms but got only 1 student. We had informed many people in many ways to inform students …. We did not get students who are ready to learn for free. So I am sure these lectures are NOT FREE. If anyone learns from these, s/he changes and that’s the gain / benefit. This change ( due to learning ) is very costly …. Most do not want to learn ………..
4 ) How can I get all your lectures ?
Ans : – Apart from my lectures there are approx 450GB of PCM ( Phy, Chem, Math ) lectures free in the net. It takes approx 1 year of continuous download from scattered sources. I have Thousands of these. You can take ALL of them free from me in an external 500 GB hard disk, instead of spending so much money and time again for downloading. These cover ( by Various Professors ) everything of Chemistry, Physics, Maths… Most of this is from outside India … as foreigners have much wider heart than India ( as most of GNU / open source software have been developed by Non-Indians ). I observed the gaps in these videos, and solving IIT, APhO, Roorkey, IPhO Numericals. Videos made by me along with these videos gives a complete preparation. Write a comment in this page to contact me.
5 ) How do you get benefited out of this ?
Ans :- If anyone learns we all will have better people in this world. I will have better “ YOU “.
6 ) Why do you call yourself a Zookeeper ?
Ans :- This is very nicely explained at http://zookeepersblog.wordpress.com/z00keeper-why-do-i-call-myself-a-zoookeeper/
7 ) Where do you stay ?
Ans :- Presently I am in Bangalore.
8 ) If I need videos in a few topics can you make them for me ?
Ans :- Yes. You have to discuss the urgency with me. If I am convinced I will surely make these quickly for you and give you and ALL. I teach both Maths and Physics. So anything in these 2 subjects are welcome.
9 ) Why did you write an article saying there are No Poor students ?
Ans :- There are lots of NGOs and others working for rural / poor children education at lower classes. While very less effort is on for std 9 till 12. Also see the answer in question number ( 3 ) above. In last 20 years of teaching I never met a Poor child who was seriously interested in ( higher ) studies. As I have a mind / thinking of a ” Physicist “, I go by ” Experimental Observation “.
It is not about what is being said about poor in media / TV etc, or ” what it should be ” ( ? ) …. It is about what I see happening. Also to add ( confuse ? you more )…. You must be knowing that in several states over many years now girl students have better ( by marks as well as by pass percentage ) result in std 10 / Board Exams….. well but NEVER a girl student came FIRST in IIT JEE … why ? [ The best rank by a Girl student is mostly in 2 digits, very rarely in single digit ] ????? So ????
10 ) How much do I have to study to make it to IIT ?
Ans :- My experience of Teaching for IIT JEE since last 20 years, tells me, Total 200 hours per subject ( PCM ) is sufficient. If you see my Maths and Physics videos, each subject is more than 200 hours. So if someone sees all the videos deligently, takes notes and remembers, …… Done.
11 ) What is EAMCET ?
Ans :- Engineering Agriculture and Medicine Common Entrance Test is conducted by JNT University Hyderabad on behalf of APSCHE. This examination is the gateway for entry into various professional courses offered in Government/Private Colleges in Andhra Pradesh.
12 ) In your videos are you covering other Exams apart from IIT ?
Ans : – Yes. See many videos made by solving problems of MPPET, Rajasthan / J&K CET, UPSEAT ( UPES Engineering Aptitude Test ), MHCET, BCECE ( Bihar Combined Entrance Competitive Examination Board ), WB JEE etc
13 ) What is SCRA ?
Ans : – Special Class Railway Apprentice (SCRA) exam is conducted by Union Public Service Commission (UPSC) board, for about 10 seats.That translates into an astonishing ratio of 1 selection per 10,000 applicants. The SCRA scheme was started in 1927 by the British, to select a handful of most intelligent Indians to assist them in their Railway Operations, after training at their Railway’s largest workshop, i.e. Jamalpur Workshop, and for one year in United Kingdom. The selected candidates were required to appear in the Mechanical Engineering Degree Exmination held by Engineering Council (London).
