AIEEE-08

2009-04-21T22:43:00.001-07:00

The All India Engineering Entrance Examination (AIEEE) was held all across the country today, ie. the 27th April 2008.
AIEEE 2008 consisted of 105 questions of 3 marks each – 35 questions each in Physics, Chemistry and Mathematics to be answered in 3 hours. Among the several versions of the question papers, the order of the options was also jumbled. The overriding emotion that ruled the majority of the students coming out of the examination venues at 12:30 pm was one that of content and satisfaction. AIEEE 2008 did not burn the psyche of a well-prepared student. Most of the students felt that the paper was a well-balanced one with a good mixture of questions of various difficulty levels. There were two sets of cluster (paragraph) questions in Physics – a new avatar in AIEEE examination. The two sets of paragraph questions had three and two questions respectively. Assertion-Reasoning Type Questions appeared in the Physics and Mathematics sections. Among the three subjects, the Chemistry was relatively the easiest. Though there were several "thought provoking questions" whose time-investment per question was almost double the average. Well prepared students enjoyed the challenge, though and came out performing very well in this subject.
So if you feel you have done well, is it time to celebrate? Well, for a start, we suggest you carefully study the Answer and Solution for AIEEE 2008 provided here. Then consider the fact that the number of questions was less that of AIEEE 2007. And then consider the fact that the number of students appearing for this examination has seen an increase over the pervious year..
So where does that leave you? Under the circumstances described earlier, each mistake is going to be more costly. Don't feel bad by looking at the negatives you may have accumulated. If you have done justice to your preparation for AIEEE, let the natural laws governing work and reward take care of the situation from here on. At the same time, do plan ahead for the other Engineering Entrance Exams. The next big ticket examination coming your way is the BITSAT. You will really require good practice for this online examination.

CRACK AIEEE 2009

2008-11-04T07:09:00.000-08:00

First of all, whenever somebody has any ambition or aim to do something, he or she should be confident to do that thing, means never lose HOPE.

FEW MANTRA TO CRACK ENTRANCE EXAM

FOR IIT-JEE: For the preparation of IIT-JEE, you have to clear & enhance your CONCEPTS. All you have to go through more and more CONCEPTS.

Whenever somebody prepares for IIT-JEE, just always be with THREE THINGS:

>First is: BUILDING THE CONCEPTS,

>Second is: PROPER APPLICATIONS OF CONCEPTS &

>Third is: PRACTICE.

Here remember, I stressed on the word 'PROPER'. In Physics, building CONCEPTS is not a tougher job but building RIGHT (PROPER) CONCEPTS is much tougher. Out of every 20 students, I guarantee, that there is only one or two students who know the RIGHT CONCEPT about a particular topic. So I would like to say that don't think Physics is a tougher subject. REMEMBER one more thing if I prefer even a single book, so it means you have to go through each & every line of that book starting from first page till you encounter the last page. There is no use of doing a lot of books only for one subject without getting any point. I saw a lot of students having their own library at their home. But as far PRACTICE is concerned, do whatever you get from anywhere. Whereas in case of Chemistry, just you need to put your efforts on PRACTICE in case of Inorganic Chemistry. In case of Organic part, just first build up your all BASIC Reactions, then start do PRACTICING. And for Physical Part, same thing you have to do as in case of Organic Part. For Maths (My favourite Subject), just use your brain as much as you can. Ultimately for preparation of any exam, remember some points:

1) Always start from BASICS because "without base, there will be no altitude" and "journey of a thousand miles begin with single step".

2) Always BUILD UP RIGHT & APPROPRIATE BASICS because "once the track of train is being changed, it will go on only that track". So always select the right track.

3) Never prefer solutions of questions before doing SELF-ATTEMPT at least five times till you get the right answer because "without fall you can not stand at once".

4) Never leave the question in between. And I saw a lot of students practicing this question without attempting it whole, and it's a very big fault for students and even it becomes their negative point sometimes. So please ignore this thing. Because "many of life's failure are people who did not realize how close they were to success when they gave up"

5) Always try a question with CONCEPTUAL APPROACH, not just read the question then start doing without getting the point that what question is saying.

6) Your study schedule should be such that you will even easily get the time for a little enjoyment daily.

7) Most important thing is that you should be having a time schedule as well as REGULARITY in study.

8) Also you will have to take appropriate sleep or rest of at least 6 hours a day if you are preparing for IIT-JEE otherwise your mind set-up for next day will not be in place.

9) Never cram the things, always TRY TO UNDERSTAND the problem or theory.

10) And BE CONFIDENT while you are preparing. NEVER LOSE CONFIDENCE.

11) Always keep contact with intelligent students of your class or at coaching centre.

12) For your brain storming, I always preferred MTG publications monthly magazine in maths part.

13) Always be AHEAD in exams like-OLYMPIAD, UNIFIED COUNCIL etc. Etc. (for more information-contact me)

14) Always keep the copy of latest syllabus for particular exam. Always check the syllabus before starting a new topic.

15) NEVER GET DEMORALIZED BY SOMEBODY but yes ALWAYS GET INSPIRED FROM SOMEBODY WHO IS YOUR SENIOR. (If you want, contact me)

16) I have a positive point i.e. once I set a goal, then I don't look at anything else, I just KEEP DETERMINATION in me until or unless I ACHIEVE THAT GOAL.

17) Whenever you complete any chapter or particular topic, first of all, go through that topic from NCERT. (It's very important).

18) There is one more thing, whenever you are studying just be CONCENTRATE on that thing so badly, so that you even don't know what is happening your nearby. Because studying 2 hours with DAMN GOOD CONCENTRATION is equals to studying 5-12 hours without any concentration.

19) Always study anything with GREAT INTEREST otherwise it will be of NO USE.

20) Even there are some students who think that they can nod prepare for IIT-JEE like EXAMS. So if they think so, then they are wrong. Because "ATTITUDE, NOT APTITUDE DETERMINES ALTITUDE".

At last I prefer books for preparation of IIT-JEE subject-wise (according to me):

*MATHS: R.D.SHARMA (for theory and practice) and PURUSHOTTEM KUMAR-OBJECTIVE (it must be for practice)

*PHYSICAL CHEMISTRY: BHARTI BHAVAN PUBLICATIONS, R. C. MUKHERJEE (NUMERICAL CHEMISTRY), DR. P. BAHADUR,

*ORGANIC CHEMISTRY: NCERT (must), SOLOMONS, IIT CHEMISTRY

*INORGANIC CHEMISTRY: NCERT (must) (you need nothing else for preparing this part)

*NOTE: prefer MTG Publication monthly Magazine also &if are taking coaching from somewhere, then prefer that notes also.

*PHYSICS: H.C.VERMA (part 1 & 2 both)(for theory as well as practice), IIT GALAXY (VOL 1 TO 5),

At last I want to say one more thing for IIT-JEE that "DO PRACTICE AS MUCH AS YOU CAN WITH YOUR FULL EFFORT"

FOR AIEEE: There are lot of students who think that if they are preparing for IIT-JEE, then they are also preparing for AIEEE. It's wrong.

First of all, for preparation of AIEEE, they have to prepare tightly for CBSE EXAMS if the person is fresher otherwise dropper also have to prepare for CBSE, only then he can think of rank less than 20,000 in AIEEE.

If somebody is preparing for AIEEE (whether he is preparing for IIT-JEE or not), he or she has to keep THREE WORDS IN HIS OR HER MIND ALL THE TIME:

1) PRACTICE(as much as somebody can)

2) SPEED(for doing question with RIGHT APPROACH)

3) ACCURACY(the MOST IMPORTANT POINT to get the RIGHT ANSWER)

For AIEEE, you have to learn SMALL TRICKS and MAGIC to solve the question in possible time.

All other things are in same pattern as that of IIT-JEE.

<<<<>>>>

##CAN YOU TELL ME THE DIFFERENCE BETWEEN A GOOD TEACHER AND THE BEST TEACHER==? (Can u guess)???

If answer is NO, then READ THIS : THERE WILL BE NO DIFFERENCE HOW THEY ARE TEACHING THEIR STUDENTS,BUT THE ONLY DIFFERENCE IS THAT HOW ANY TEACHER IS CREATING INTEREST IN PARTICULAR SUBJECT AND HOW THAT TEACHER IS MOTIVATING AND INSPIRING THE STUDENTS TOWARDS ACHIEVING THEIR GOAL.

Somebody said right that: "ANYBODY CAN TEACH BUT EVERYBODY CAN NOT STUDY".

SO, there MUST be PROPER WAY TO TEACH SOMEBODY.

THERE ARE A LOT OF THINGS TO TELL BUT THIS IS ARTICLE!

THESE ALL BAD RANKS ARE DUE TO THE REASON THAT I DID NOT FOLLOW ALL THE POINTS I EXPLAINED ABOVE.

SO, DON'T YOU DO THE SAME MISTAKES ,IF YOU WANT TO BE IN TOP 500 HUNDRED RANKS OF IIT-JEE, BITSAT AND AIEEE!(guarantee)

CARBOHYDRATES - Classification: aldoses and ketoses; monosaccharides (glucose and fructose), constituent monosaccharides of oligosacchorides (sucrose, lactose, maltose) and polysaccharides (starch, cellulose, glycogen).

Carbohydrates are classified as:
Monosaccharides

Oligosaccharides

Polysaccharides

Monohydrates may be represented as follows
H
!
C=O
!
(H-C-OH)-n
!
CH-2OH

A polyhdroxy aldehyde

CH-2OH
!
C=O
!
(H-C-OH)-n
!
CH-2OH

A polyhdroxy ketone

Monosaccharides are named as follows.
1. The calss name of monosaccharides begins with the prefix 'aldo' for polyhydroxy aldehydes and "keto' for polyhydroxy ketones.
2. the name ends with suffix 'ose".
3. In between prefix and suffix, the number of carbon atoms (i.e. di, tri, tetr etc.) is inserted.

Reducing and Nonreducing Sugars

Reducing sugars are easily oxidized to give carboxylic acid.

They reduce
(i) Tollens reagent (an ammoniacal solution of silver nitrate) to shiny silver mirror.
(ii) Fehling's solution (an acqueous solution of cupric iron and tartrate salts) to red precipitate of cuprous oxide, and
(iii) Benedict's reagent (an alkaline solution containing a cupric citrate complex) to red precipitate of curous oxide)

All aldoses are reducing sugars, but some ketoses are reducing sugars as well. For example, fructose (a ketose) reduces Tollens reagent. This occurs because fructose is readily isomerized to an aldose in basic solution.

amino acids are organic compounds containing both an amino group (NH2) and carboxylic group (COOH). They are represented by the general formula:
R

C-COOH

NH2

Essential amino acids

These amino acids are required by the body but are not made by our bodies. hence they must be supplied in diets.

Valine
Leucine
Isoleucine
Phenylalanine
Methionine
Trptophan
threonine
Lysine
Agrinine

L-Family of Amino Acids
With the exception of glycine, all other α amino acids have chiral carbon atom and have two optically active isomers.

However all naturally occurring amino acids belong to L series which have -NH2 group on the left.

Structure of Amino acids

amino acids exist as dipolar ion called a zwitter ion.

i) when an acid is added to an amino acid-COO- accepts this proton and therefore the basic character is due to -COO-group.

ii) When an alkali is added to amino acid -NH3+ group releases the proton and therefore acidic character is due to -NH3+ group.

Peptide

peptides are compounds formed by the condensation of two or more same or different α amino acids. The condensation occurs between amino acids with the elimination of water. In this case,the carboxyl group of one amino acid and amine group of another amino acid gets condensed with the elimination of water molecule. The resulting C-N linkage is called peptide linkage. The bond of C with O becomes a double bond.

The formation of peptide can be between two amino acid molecules or the number can go on until a single molecule containing several hundred thousands of aminoacids is formed.

Proteins

Structurally, proteins are long polymers of amino acids linked by peptide bonds

EXPERIMENTAL SECTION - (ACCORDING TO NEW SYALLUBUS)
Preparation of Ferrous ammonium sulphate (Mohr’s salt)
Ferrous ammonium sulphate (Mohr’s salt)

It is a double salt. A double salt is a substance obtained by the combination of two different salts which crystallize together as a single substance but ionize as two distinct salts when dissolved in water.

Mohr’s salt is prepared by dissolving an equimolar mixture of hydrated ferrous sulphate and ammonium sulphate in water containing a little of sulphuric acid and the crystallization from the solution.

On crystallization light green crystals of ferrous ammonium sulphate separate out.
