Keep it simpleAs you are required to solve 150 questions in 180 minutes, the difficulty of questions is kept low & they are framed so as to be solved quickly. Speed and accuracy both hold important. I suggest you to be at ease, relax, keep confident and work at your natural speed. A conscious effort to increase speed may lead to a poor accuracy. Also, DON’T KEEP YOUR EYES FIXED ON THE WATCH, it will only create panic.About the questionsBooks Suggested: NCERTsAs far as individual subjects are concerned – in PCM, the questions are mostly straight forward and directly formula based. All you have to take into consideration is you should never start attem

I am enjoying this rainy season and recollecting some sweet memories of my stay in Kota where I was studying in Bansal Classes. One day, during the regular classes, Amit Gupta sir (B.Tech., IIT Delhi) discussed a puzzling story with us… "One day, when I was a third year student, one of my friends woke up very late (as usual in IITs). He got ready quickly without having his breakfast and rushed to his department from his hostel premises. When he entered the building and pushed the lift button he knew by that time the classes must have been started. Then suddenly what happened!

Hi.. I would give like to speak my hearts out for Bansal and IITJEE preparation....I was in Bansal during my drop in IITJEE... The institute is grand,dedicated, devoted, determined for its students to get into the IITs'.But let me tell u.. they dont hv a magic wand to turn a JEE aspirant into a JEE QUALIFIER.... They hv d word power to encourage students to study for IITJEE when they get depressed.. Teachers are attached to students for their preparation...But, some cannot afford to go to Bansal for the following reason that I have identified:-1) Emotionally attached to home, parents, siblings,etc..

Trick 1 : Multiply any two numbers from 11 to 20 in your head.
Take 15 x 13 for example... Place the larger no. first in your mind and then do something like this Take the larger no on the top and the second digit of the smaller no. in the bottom.
15
3
The rest is quite simple. Add 15+3 = 18 . Then multiply 18 x 10 = 180 ...
Now multiply the second digit of both the no.s (ie; 5 x 3 = 15) Now add 180 + 15. Here is the answer 180 + 15 = 195 . Think over it. This is a simple trick. It will help you a lot.
Trick 2 : Multiply any two digit number with 11.
This trick is much simpler than the previous one and it is more useful too. Let the number be 27 . Therefore 2

Structures With Bidentate Ligands Bidentate ligands are Lewis bases that donate two pairs ("bi") of electrons to a metal atom. Bidentate ligands are often referred to as chelating ligands ("chelate" is derived from the Greek word for "claw") because they can "grab" a metal atom in two places. A complex that contains a chelating ligand is called a chelate. Some Bidentate Ligands ethylenediammine(en) acetylacetonate ion(acac) phenanthroline(phen) oxalate ion(ox) ethylenediammine (en)Ethylenediammine is a neutral molecule containing two N atoms that can each donate a pair of electrons to a metal atom.

More than half the students that you generally meet have really not begun their IIT JEE preparations in full swing. Most of them are half stuck in either Rotational or in Gravitation. In Mathematics, they are really not well prepared. Either they have just finished most of AP, GP and HP or have just done some differentiation. In Chemistry things are generally better but then still not up to the mark. If you happen to be one of these then this is very important for you. The first and foremost thing is to start realizing that Mechanics alone will take you no where! You have to start working on Electrostatics, Current Electricity, Modern Physics, Optics, Hea

JEE is an exam which requires a high level of perfection in all respects - particularly in memory, logic, speed, and quantitaive analysis. Such perfection requires constant practice. Here, I would like to provide tips which may help my friends clear this exam.Disclaimer: Though I have got a good rank of 96, my beginning (from X) was pretty ordinary - so I expect this guide to help the majority of students. Also, since I'm not a qualified instructor, I can only give my personal point of view.Books:Maths - Any good book will do, just as long as it has thousands of problems (I'm serious).
