For GMAT aspirants looking for tests and practise sets online, there is a thing to rejoice. GMAT Club has around 25 Math and 6 Verbal tests online. One each from Math and Verbal are free. But to access the rest, you need to shell out around $80 or have significant participation in the forums: (a) 50 kudos (b)100 posts with25 kudos or (c) 200 posts and 90+ days of membership.
The good word is that the website has decided to give open-access to all the online tests on holidays (starting Christmas 2009). It is a good way to get a sneak peek on the quality, difficulty and pattern of these tests. The next upcoming holiday is MLK on 18th Jan.
Happy Testing!

English Grammar - Incorrect Usage 1
'Graduated' or 'Graduated from':
Correct Usage: 'Graduated from'.
It is a common error to use 'graduated college'. It should be 'graduated from college'. 'To graduate' is a verb. It can be both transitive or intransitive. A transitive verb takes an object and an intransitive verb doesn't.
Consider the following example.
Raj graduated from University of Cincinnati.
This sentence uses an intransitive form of 'to graduate', because this verb has no object. 'from University of Cincinnati' is not an object. It is a prepositional phrase that tells you more about where Raj graduated from. But consider this sentence.
Raj graduated University of Cincinnati.
'To graduate' is turned to a transitive verb. The act of graduation is something a school does to a student and not something a student does to school. Schools graduate students. For example,
University of Cincinnati graduated 800 students this year.
However, in the sentence 'Raj graduated University of Cincinnati', 'Raj' is the subject and 'University of Cincinnati' is the object. So, while 'Raj delighted University of Cincinnati' is gramatically correct, 'Raj' cannot graduate 'University of Cincinnati'.
So, 'graduate from' is correct.
Raj graduated from University of Cincinnati. <>
Raj graduated University of Cincinnati. <>

Best of CAT (Common Admission Test) - 1
After a relatively refreshing hibernation, I am back to my web log to write a simple terse article, which is the beginning of a series of such articles that deal with some of the best CAT puzzles I encountered. Computational Mathematics - a domain that I am wildly passionate about, is trying to solve these puzzles in both theory and programming. I will start off with a very simple CAT problem that I encountered sometime back. It was rather interesting and deals with Number Theory, which is one of my favorite areas in Mathematics. I transitioned this logic in C++ and it was truly a good exercise.
It is to determine number of zeros in a given number's factorial. Determining the number of zeros in say, 10! is pretty straightforward. But to determine number of zeros in 100! for example is unwieldly - especially from an examination point of view.
Question: What are the number of zeros in 100!
Solution: To determine number of 0's, it is equivalent to determine how many 10's make up the number. For that 10 = 2 x 5 and (2,5) are co-prime. Hence the number of 10's in number N can be determined by N/5 + N/5^2 + N/5^3+ ..... + N/5^n, as long as N/5^n > 1. '^' stands for exponential operator.
=> 100/5 + 100/5^2
=> 20 + 4 = 24.
Answer: 24
I built this into C++ and the code is intuitive.

I will keep posting similar problems (especially from CAT) and I believe this would be mutually beneficial.

ISB in Top 20 (!)
Though I am not a firm believer in MBA rankings, I definitely welcome the Financial Times MBA rankings to place ISB (Indian School of Business) 20th best B-school in the world. ISB ought to receive recognition for its innovation, boldness and strategy. I reserve my judgment if it is really worth to be in the Top 20 and at the outset, it appears to be a bit premature. But, as is true with other rankings, there is no smoke without fire and FT has numbers to give this rank to ISB - which is great.
In recent times, the credibility of MBA rankings has surely taken a beating. Major reason is the mushrooming of sources that issue the rankings. It is surprising to see London Business School in #2, ahead the likes of Harvard and Stanford. But, FT is based in London and so may be they had other assessments too (?). Wharton leads the race for the umpteenth time.
Coming to India and ISB, I believe the diverse class profile, course delivery, cost of the program, duration and the return of investment worked in its favor. The average GMAT for the incoming class is high compared to most other schools in the FT list, which is largely driven by Indian applicants. It is an unprecedented and truly remarkable achievement for the six-year old school. One reason why the IIMs missed the bus, to me, is their over dependence on CAT for admission which eliminates any chance of diversity. I have high regards for CAT (it is the toughest entrance exam to crack) but I feel if IIMs reduce the weightage for CAT (and not compromise on the cut-offs and thus the quality of intake) and implement the currently non-existing requirements like admission essays, work experience in selecting the class, then they (A,B,C) would be on par with the best.
Anyways, it is great to have an Indian school in the list and it only increases ISB's responsibilities to maintain its standards and surge ahead.
