Do grades or CGPA really matter for engineering students? How much CGPA on average is good or required for a better job in future? These are different and mostly asked questions by engineering students about grades or CGPA. It goes a common saying during the college life that those getting higher GPA’s are deemed to get the best jobs right after graduation and with Steve Job’s statement of ‘Be nice to nerds, you might end up working for one’ adds more spark to the argument.

Study, study and just study is what everyone is told of during the whole tenure of engineering degree to the students. Many universities cut off their student’s social activities, intra university groups and sports, just for the fact that they do not deviate from the path they are supposed to adopt. There remains no doubt that studies remain an integral part of a student’s curriculum, with engineering being a filed requiring high level of observance and a purview requiring students to think out of the box for solution of complex problems. Education makes a person well versed with knowledge of subject, academics, formative effect of mind and physical ability of an individual.

However, Engineering clearly needs knowledge beyond the scope of books to a great extent, which a four-sided classroom may not be able to provide. While studying this domain, one has to have a horizon of how things happen to be in real world and simulation of the effect can be observed clearly with social activities happening around them. Education undoubtedly makes a person well versed with knowledge of subject, academics, formative effect of mind and physical ability of an individual.

Do grades or CGPA really matter for engineering students? It depends on what you want to do in future after completing your engineering degree. Do you want to do a job or do you wish to continue education? It continues to be a common myth over the years that higher the GPA you get out of college, a higher salary job will be looking your way. The statement is clearly misleading and should not be made a rule of thumb under any circumstance whatsoever. A good GPA does come in as criteria for initial screening at interviews where the recruitment managers get a number of resume from where they need to choose student to avoid the entry of a slouch personnel but there a number of other factors that constitute to your selection. Even if you are not good at scoring high Grade Point Average, and consider yourself to be a practical person fully equipped with pragmatic skills and an attractive work/internship experience, you can knock down your opponent and overshadow his chance of clinching the gold. GPA does come into account with a large extent while an undergraduate student applies for high education. Due to the ample amount of applications that graduate universities receive throughout the year from around the globe, usually a GPA cut off is made and a threshold is marked as an entry criteria. Even that could be beaten with the conditions of extracurricular excellence being at the top notch level.

A large number of industries do not bother to look at a student’s GPA or even their transcripts if the candidate is able to clear their assessment skills test and screening interview. With that being said, it is prudent to note that your educational institute’s label does count into account if your GPA score is not high along with projects and coursework assignments. It must be noted down that regardless of the job market, securing a GPA and concentrating on studies should always be a top priority for every student irrespective of what field he chose to adopt.

What are Hydrogen fuel cell cars/vehicles? Hydrogen can be used to power vehicles in two ways. It can be burned using a hydrogen internal combustion engine (sometimes called an H2ICE), which is basically a modified gasoline engine. It can also be used in a fuel cell.

Unlike a traditional car engine, a fuel cell does not burn fuel and has few moving parts. Inside the fuel cell, a chemical reaction takes place that converts the chemical energy of a fuel into electricity. Fuel cells are a little bit like batteries, except that you never have to charge them. To keep them operating, all you do is provide a constant supply of fuel. For automobiles, that fuel is hydrogen.

Fuel cell cars can be refueled in about 5 minutes, just like today's cars. And just like a common hybrid, the fuel cell car stores energy captured during braking and deceleration in a battery to improve efficiency.

Hydrogen fuel cell

Hydrogen fuel cell vehicles are zero emission and run on compressed hydrogen fed into a fuel cell "stack" that produces electricity to power the vehicle. A fuel cell can be used in combination with an electric motor to drive a vehicle – quietly, powerfully and cleanly.

How It Works

An individual fuel cell consists of two electrodes, one positively charged (cathode) and one negatively charged (anode), with a substance that conducts electricity (electrolyte) sandwiched between them. Oxygen from the air passes over the cathode and hydrogen over the anode, generating electricity and water. The hydrogen fuel for a fuel cell electric vehicle can be supplied in several ways. Most vehicles carry a tank of pure hydrogen. Individual fuel cells must be combined into groups called fuel cell stacks in order to achieve the necessary power required for motor vehicle applications.


Most automakers have placed fuel cell vehicles with customers, and many plan to introduce fuel cell vehicles to the early commercial market around 2015. Transit agencies have been operating fuel cell buses in revenue service and are moving to next-generation technology. Customers have been fueling at private, fleet demonstration stations, and are awaiting a retail-ready network.


Since fuel cells and hydrogen fueling infrastructure are in the early stages of development, the cost of both the vehicles and the fuel are quite high. However, when fuel cell vehicles hit the showrooms and the fueling infrastructure is in place to meet the demand, the cost of both the fuel and the vehicles will be comparable to their gasoline counterparts.


Hydrogen fuel cell cars are eligible in California for single-occupant HOV lane use .


Currently, there are over 25 research, public and private hydrogen fueling stations operating in California with several more in the planning or development stages. Below are some resources for finding fueling stations for hydrogen fuel cell cars.


Hydrogen fuel cell cars are quiet, very energy efficient, have zero emissions and have equivalent range and performance as their gasoline counterparts.


When operating directly with hydrogen, there are no polluting emissions and no greenhouse gases from a fuel cell – only water and heat. If the hydrogen is generated by reforming fossil fuels, some greenhouse gases are released, but much less than the amount produced by conventional vehicles. In addition to these benefits, fuel cells could dramatically reduce urban air pollution, decrease oil imports, reduce the trade deficit and produce American jobs.

The Global Warming Score for fuel cell vehicles reflects the upstream greenhouse gas emissions associated with producing the hydrogen used in these cars. Using the current adjustment factors, fuel cell vehicles have a Global Warming Score of 9. This adjustment factor will be revisited at a later date to reflect the newer state of the technology which may lead to an improved Global Warming Score for these cars.
Hydrogen Production

Hydrogen can be produced from many domestic feed stocks, such as natural gas and renewable resources like water, using electrolysis. While the most common method of making hydrogen, using natural gas reformation, results in fewer smog-forming and greenhouse gas emissions than traditional vehicles, California is working to increase use of renewable production sources.

The Global Warming Score for hydrogen fuel cell vehicles reflects the upstream greenhouse gas emissions associated with producing the hydrogen used in the vehicles, therefore you may notice that these vehicles receive a Global Warming Score of 9 even though they are zero emission vehicles. These adjustment factors will be revisited at a later date which may lead to an improved Global Warming Score.

Perks & Conveniences

Fuel cell engines offer a combination of the range of conventional combustion engines with low fuel consumption, minimal or no harmful emissions, low noise emissions, and the comfort of an electric vehicle.


Fuel cell cars are being developed with levels of safety, comfort, and cost comparable to those of a conventional vehicles. Like all fuels, hydrogen has energy and needs to be treated with respect. Because hydrogen is lighter than air it disperses very quickly. Manufacturers are committed to building fuel cell vehicles that meet or exceed safety standards.


As boil off, a process which is difficult to avoid. When the car is not in use for as little as one day the liquid hydrogen begins boiling off. Half the fuel is gone in eight days time. Therefore, this car is actually more efficient on the road than in parked in a garage.

There are some software which are very basic and common for every engineer to learn. When someone says that a modern day engineer should be well versed with various engineering software, it wouldn’t be wrong at all. As the time is passing in a haphazard manner and survival is only for the fittest in the market, one has to be fully equipped with latest software operating in day-to-day use.

The foremost and most common software package that every engineer rather every common man must learn to use is Microsoft Office. With Microsoft launching repeatedly newer versions of its suite, the necessity of learning the basics increases. Microsoft Word is the most widely tool used for documentation, reporting, grant approval, feasibility reports or even if a small application is to be written for inter-departmental purpose. While talking of transactional study, no tool is in the line with Microsoft Excel which lets you develop spreadsheets and reports with easy to use facilities. Till date no tool has grasped the market share in offices than Microsoft Powerpoint to built slides for presentation purposes. With the inclusion of top down and font effects, you can easily customize your work as per your needs. MS Outlook is also widely used in offices as a source to mailbox configured as per the office requirements.

Every engineering student irrespective of his engineering degree and university is rightly taught the knowledge of computer programming. It is the utmost level of assignment that is instructed to student primarily for the purpose for logic development. It is only after graduation that a student realizes the use of studying programming; you get to know the insight behind the development of a certain object. Hence C/C++ programming is a great software for engineers to learn and ponder upon. It inculcates the sense of constructing something at your own and nourishes an individual’s potential.

AutoCAD is effective and very common engineering software taught at basic level to the junior classes of engineering just to get them hands on experience when they go into the market. People strongly believe that it is a tool dedicated purely to the mechanical and civil engineering intentions; however they do not realize that by designing a project on this applied software, you get to broaden your vision when you make objects as per your imaginations.

Project Management tools such as Primavera and MS Project are a must need tool for every engineer. They let you design a plan for assessing the budget and allocating your resources as per the workload management. With the help of Primavera, a manager can work on improving his team’s collaboration, prioritize project and conduct risk analysis to enhance the earned value management. In the same way, MS Project creates an event based chain methodology to help a manager visualize the effect in a Gantt chart.  Both these tools help effectively in the enterprise project portfolio management.  Above all, every such tool which helps in easing an engineer’s task at a minute level which might make a difference later on in project’s completion.
