Last minute subject wise preparation for IIT-JEE
In the last few days of your preparation for IIT-JEE, you will be touching on last minute topics. But, that should not lead you to ignore the basics, and neither should you skip revising. Here is a brief look at subject wise prepartion.
Chemistry: Most students who do well in IIT-JEE insist that there needs to be consistent focus on Chemistry, because it is quite different in nature from conceptual Physics or Mathematics. Experts suggest keeping focus on both Organic and inorganic chemistry. Focus areas in physical chemistry are electro-chemistry, thermodynamics and chemical equilibrium. In inorganic chemistry, focus on qualitative analysis, co-ordination chemistry and chemical bonding. While you work with numbericals, watch out for carelessness which might lead to calculation errors.
You should keep in might the reaction groups, species/ functional groups that occur as reactants and those that occur as resulting compounds, catalysts and reaction conditions. Understand the arrow mechanisms.
Mathematics: Be careful about co-ordinate geometry(circle, and other open curves) and calculus related questions. For integration (in calculus), try to work out as much mentally without help of references as possibel. Similarly some focus is required on quadratics equations, complex numbers, and probability. In algebra, some stress on vectors and matrices is quired, and similarly conic sections in trigonometry.
Physics: This subect is more conceptual and intuitive, and ideally you should find it hard to forget. Be perseverant and follow through till the end. Mechanics, Thermodynamics, Fuilds, Heat, Sound are important. And similarly electronics and basic magnetics, electro magnetic induction are important in Electric. Be very clear about Optics concepts.
The 3-H principle
The education system in India though widespread, is not really as effective as we or even the government would want it to be. Many of our students seek admissions in institutions outside the country. And of course, more and more students seek admission in non-government schools. The ailments are many, as are the solutions. Lack of effective and trained teachers has been a perpetual pet peeve of many. Similarly, most of us keep complaining about lack of innovation in our schooling system or from the government bodies.
But, there are some exceptions. Just before visiting Delhi one time, I sent out emails to publishers that we wanted to tie up with so that we could fix meetings. One of those emails was sent to the workshop department of NCERT to locate and learn more about what they call school kits. One Mr Hari Gupta (head of the workshop department) wrote back mentioning that he was happy to meet.
After some logistics related conversations, we landed up to see Mr. Gupta a quarter hour late for the appointed time at 5.45pm on the particular day. We reached his office on time, but were told by the hangers on "Gupta sahab to bahut pehle ghar gaye" (Mr. Gupta has left for home long back). We were a bit disappointed, but still did call him on his cell phone. To our delight Mr. Gupta informed us that he will be back in his office in 10 minutes. We walked into his large almost typical government office and waited. The large desk had a PC, a printer and bunch of files, sheets of paper and all that you would expect. That is where the similarity with a babu's office ended. The other side of the large room had cupboards, and there were large desks with boxes, and laboratory equipment. Just that the laboratory equipment (pipettes, burettes, test tubes etc) seemed from liliputland. While we waited curious, Mr. Gupta showed up.

Molecular Model Kit
We spent time explaining what KOOLSKOOL was about and what we were setting out to do. Mr. Gupta's team designs, prototypes and manufactures (on a very small scale) Mathematics, and different science kits for schools. These include laboratory in a box which caters to four students at a time, molecular structure kits, advanced kits for higher classes. The chemistry kits have miniaturized equipment, made of readily available and cheaper material. e.g. the pipette is small soft transparent plastic affair. All the kits are based on experiments or concepts from the NCERT text books and ingeniously and simply implemented.
What surprised us pleasantly was that Mr. Gupta came back from home (in the NCERT campus) to meet us, and the amount of delight and pride that he took showing us what his lab was creating. The sheer childlike delight was heartening, as was his conversation (which we could not help over hearing) with an associate who got lectured about not being confident about pushing these kits. Mr. Hari Gupta truly does believe that he is serving the nation and it is his duty (being in the position that he is) to be ingenious and help education in our country. He believes, and wants all that is lab produces to follow the "3 H Principle". The Hs as Hand, "Hurt"(that is how Mr. Gupta pronounces Heart) and Head. Mr. Gupta says - "my kits should help a student use his hands, make education practical...should delight his heart, and get him to use his head"! Simple, and beautiful isn't it?

Microscale Chemistry Laboratory Kit
Mr. Gupta will launch an expression of interest type request, for manufacturers to come forward (from different parts of the country) to manufacture at scale what his laboratory prototypes. This man, does not want to patent his creations so as not to restrict free production. Though we feel not patenting will permit manufacturers to produce and deliver sub-standard product quality. But, that is a different discussion.
We just wish, there were many more Mr. Guptas in this country, and all related to education!
