GATE Eligibility - No to 3rd Year Students in 2012

I first read about change in GATE eligibility in Prof. Giridhar Madras's blog. I talked to a few colleagues at IITK also, and like the comments in that blog, here too I heard that the major reason for not allowing 3rd year students to give GATE was that they can't handle so many students.

This is yet another manifestation of the arrogance of IITs. If you can't conduct this exam, then give it up. It is not your exam. It is MHRD's exam. This is not just for admission to IITs and IISc. This is for admission to ALL MTech programs in the country, where the stipend is charged to MHRD. CBSE has had no problem in conducting an exam for 12 lakh candidates, and should be happy to conduct yet another exam. CBSE has done a far superior job of conducting AIEEE than IITs have done for JEE (at least the way exam is conducted - I don't want to digress by discussing the paper content). And I am sure CBSE can do a far better job of conducting GATE than IITs can. If CBSE refuses to conduct, then we can consider outsourcing it to BITS Pilani, Merit-trac, Prometric, and any number of other players. All of them have huge experience of conducting large public exams.

Have IITs ever bothered to ask other universities when GATE should be conducted. Note that IITs have a small number of MTech seats. Others admit more MTech students than IITs do. But there is no mechanism for anyone to give any inputs. Most universities would want to start the admission process earlier than April, and therefore, would want GATE to be held earlier than February. But IITs won't listen. I know of some places who were seriously considering keeping some seats for "early admission" for those who would have given GATE in the 3rd year. But that won't be possible now.

GATE has also become a way to test your basic knowledge in your field of engineering. Many students would give GATE in the 6th semester, and if they get good score, highlight that in the CV for placement. The industry values such students, but this can't be done any more.

In fact, even at IITK, if someone sent us an email in March telling us that s/he has got a very good GATE score (better than our typical cutoff for calling for MTech admission), we will try our best to invite him/her for summer internship in the hope that next year s/he will join our graduate program. That would no longer be possible.

For many years, there is a talk about GATE becoming a multiple day, online exam. But trust IITs to not do that. Only a few disciplines will have an online exam even after trials for a couple of years. They are so afraid of technology.

All this because IITs and IISc can't find enough invigilators and they are too rigid to consider alternatives. They could have had, for example, more subjects in online format, and spread offline papers on to 3-4 sessions by having the exam on Saturdays as well, thereby reducing the need of faculty members going to various centers.

They have increased the cost of JEE application fee to Rs. 1800. They could have done a similar hike for GATE as well, and use that for solving problems (like going for online exams in more subjects, paying more for larger and better exam centers).

What is wrong with our Higher Technical Education

Everybody agrees that the higher technical education in our country is of very poor quality. The top 10 institutes provide very good quality education. The top 50 institutes provide good education, and everyone beyond that is bad. Talking specifically of education in IT related fields, different people talk about anything up to 80% graduates being unemployable (that is, they can't even be trained).

People from industry would love to argue that this situation has come about because academia does not listen to them. They do not have curriculum in line with industry needs. They don't teach them the latest technologies. They don't expose them to live projects. They don't put enough focus on non-technical skills like communication skills, teamwork and what not.

I have a very different take on this. It is not that these institutes (beyond top 50) are not teaching their students English, or Dot-NET, or any other latest technology. The problem is actually worse. They are not teaching them anything.

Recently, I had a chance to look at some statistics from the CS paper of GATE 2010. The average marks were 12 out of 100. This is after considering the lowest marks to be 0. (In reality, the lowest marks were -21.33.) So, if we consider real marks achieved, the average would be around 9. And the median would be even lower,
around 7 marks. More than 10% of the students had negative marks overall.

It set me thinking. What would happen if we were to ask 1 lakh 12th class students to give GATE. I would guess that unlike BTech 4th year students, the 12th class students would leave most of the answers blank (and hence avoid negative marks), and only answer those 5-7 odd questions which s/he is confident about. (There were a couple of easy questions on aptitude. There were a couple of questions on programming that 12th class students have been exposed to. And there were a couple of questions which had so much information given that one did not need to known any computer science to get those right.) My gut feeling is that if we were to give the same GATE paper to one lakh 12th class students, the median marks may be only a couple of marks less than what has been the case with these 7th semester students.

It means that 7 semesters of technical education has enabled our graduates to get 2-3 extra marks (out of 100) compared to what 12th class students can get. Remember, GATE paper is about basic computer science only. It is not about the latest technologies. It is not about industry trends.

So the problem is very simple. There is no education going on in thousands of colleges around the country. These students are not being taught even basic programming, or data structures, simple algorithms, basic computer organization concepts, etc. And hence any attempt to improve the employability of these graduates by training them in communication skills, dot-net, java, software engineering, and so on, is futile. One has to first see how we can ensure that they learn computer science basics. Unfortunately, I have no solution to offer.

Another interesting statistics from GATE 2010 paper was that in several questions, the average marks received by the students was negative. As people who have given GATE would know, you get 1 mark for the question if you answer it correctly, and -0.33 if you answer it wrongly. The scheme has been designed so that, if people were to guess randomly, then the average marks obtained would be zero. (Assuming, 1/4th of the students will answer each of the four options.) If some people know the answer and mark it correctly, some have left it blank, and others have given a completely random answer, then the average score should be positive. If we take out those who have not attempted, and those who genuinely knew the answer, and consider the rest, 75% of those should (statistically speaking) give a wrong answer. And if you add those who genuinely knew the answer, the percentage of wrong answers should be less than 75%.

But, in some questions, more than 85% people (out of those who have attempted the answer) have done it wrongly. This is too high a number (compared to 75%, in a sample of 1 lakh) to be considered a statistical anomaly. I discussed those specific questions with a few colleagues, and it occurred to us that the only reason why this can happen is if the students are not answering it randomly, but are confident of the wrong answer being right. Which means that they have been taught the subject matter of that question, but have been given wrong concept or information (which is worse than not teaching at all).

Recently, there was a proposal to have an exit test for MBBS to ensure that the degrees given by all universities in the country are adhering to a minimum quality for MBBS. I think there is a need to have an exit test for all BTech in this country. That will be a sure shot way to weed out poor quality institutions.
