The importance of Exams
Under this article, we are discussing about the various advantages and disadvantages of examinations for school students. The fever of examination can be seen running among all the students. Whenever the exams are near, a keen competition starts taking place among the students. They focus on acquiring more and more knowledge. In order to achieve anything one has to face competition. Thus, examinations help the students in preparing to become competitive. Examination is one of the best ways of knowing how much knowledge the individuals possess.
This makes the people stand out from the crowd. The more they score, the more intelligent they are considered. Thus, every student aims to study more and more in order to score excellent grades in their examinations. If there were no exams taking place, the children would have never studied and this would ruin their lives. Thus, it is very important to have examinations in order to broaden the knowledge. Examinations ultimately help in the acquiring more and more knowledge.
The acquired knowledge not only helps the students in attaining excellent grades but also aids them in developing their personality. They automatically gain a lot of confidence when they have knowledge of various fields. Thus, examinations help the students in making their personality more attractive and confident. When the students score excellent grades they are entitled to many scholarships in the prestigious colleges and universities.
Such prestigious colleges and universities help the students in securing the jobs with handsome salary packages. This helps a lot in making their future shine bright. In order to stand first in the competition, students often try to memorize the course which they are being taught in school. This limits their level of knowledge and they even do not get to understand the concepts which hinder their future growth and success.
It is an inappropriate method of testing the knowledge of the students. There might be a chance that some students did not make it to perform well in their exam due to physical illness or due to fear. This leads to a fall in their grades and they are perceived as average or below average. Exam season brings with it a lot of anxiety and stress in the lives of students. There are many students who find it very difficult to memorize the topics due to excessive stress and anxiety. Some really find it impossible to concentrate on their studies. This stressful situation make the students go bananas and they eventually are not able to perform well in their exams scoring lower grades. Each one of us is different from other in every manner. No two individuals are alike in any way.
Thus, we ought to respect the differences each one of us has. But, this is not the same when it comes to academic level. Students are often compared by their own parents and teachers on the basis of the grades they score. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

There are quite a few, but the advantages far outweigh the disadvantages.
There's a steep learning curve. You do more coding up front. Can be a tough sell to managers. Can be a tough sell to fellow developers. Improve this answer. Jaco Pretorius Jaco Pretorius 4, 2 2 gold badges 26 26 silver badges 38 38 bronze badges. These are good answers, but could be more specific about 1? Updated to give some clarification — Jaco Pretorius. If you are doing testing now the total time spent in development shouldn't change significantly. It only looks like things are taking longer because you are exposing the time it takes to write and maintain unit tests. JeffO are you familiar with the "I'm going to write myself a minivan!
It also adds to time estimates - quite correctly - so managers and customers only see the up front increase, not that the overall time is actually known for once and may even be less. If they're doing some testing then this increase will be less. Show 7 more comments. Test-first assumes you are writing code that is: testable in a unit-test manner that what you are developing has an obvious approach and will not require extensive prototyping or experimentation that you will not need to refactor too heavily or that you have the time to repeatedly rewrite hundreds or thousands of test cases nothing is sealed everything is modular everything is injectable or mockable that your organization places a high enough value on low-defects to justify the resource sink that there is something of benefit to test at a unit test level If your project does not meet those requirements you will have difficulty.
Examples: My personal best example is when writing security code for asp. Bill Bill 8, 22 22 silver badges 51 51 bronze badges. Can you give some counterexamples? When wouldn't I be writing something that is testable in a unit-test manner? Why wouldn't I be writing code that is mockable or injectable other than legacy code, which is a topic unto itself? It's like anything in this game - appropriate for many situations, inappropriate for others. Beware of anyone advocating a One True Path in any area of software development.
Especially when you are experimenting with new code and the architecture is far from clear, unit tests are just a burden and do not help to focus on the problem. They are OK as long as the solution is clear and you only have to work out the details. Show 2 more comments. Is that, perhaps, where the Michael Feathers' "new" definition of Legacy Code i. That definition wouldn't work for me : To me, any code that runs in production and that is subject of change is legacy code, independently of code or test quality. We typically associate "legacy code" with "bad code" or "obsolete code" when in reality bad code and obsolete code is already present in code under development that hasn't seen production usage yet.
Our aim should be for our code to be legacy from the get go, and to be of such quality and usefulness that it remains in usage for years, decades to come. However, there are two problems that are pretty noticeable. The test suite has to be maintained When you are serious about TDD, you'll end up writing lots of tests. Testing abstractions leak from time to time We are using Django, which has a pretty great testing framework.

Joonas Pulakka Joonas Pulakka That seems strange to me, since writing testable code usually causes me to slow down and think more about what I am coding. I actually get a bit nervous coding without tests these days. It just shows that different people indeed react differently. I'm not bashing TDD - obviously quite a few people find it useful - but the fact is that it's not for everybody. I write code better and faster without automated tests. Of course it would be absurd not to test, I just think automation is a bad choice at least for me.
I find manual testing to be both faster than maintaining a test suite and safer -- but I'm also an experienced developer so I'm very good at knowing what to test and where and why, so my code additions and re-factors are regression-free. Although I should point out that the team I work with and the projects are both small enough that I have a good sense of the entire architecture -- on a large team or a very large project, I could see automated tests as more useful, because then no single developer would necessarily be able to smell where they should be testing to avoid regressions. Are you leaving out the refactoring step?
My approach is normally: Implement something that runs proof of concept. If it works, consolidate by adding tests, improving design, refactoring. Sometimes I do not get to step 2. In this case, using TDD has turned out to have more disadvantages than advantages for me: Writing tests during the implementation of the proof of concept just slows me down and interrupts my flow of thoughts: I want to understand an idea and I do not want to waste time testing details of my first rough implementation. It may take longer to find out if my idea is worth something or not. If it turns out that the idea was useless, I have to throw away both my code and my nicely written unit tests. Giorgio Giorgio 19k 16 16 gold badges 79 79 silver badges bronze badges. It sounds like you are confusing prototype code with usable code.
Prototype code is test code. It doesn't need to be tested and you should not create tests that run against it. The step you are missing is between 1. The problem is you do not have something to consolidate, but something to write. Plan to rewrite prototype code, don't plan to reuse it. Reusing it leaves lots of place for compromise. Rewriting formalizes the split between your exploration phase and your "quality code" phase. Or rather, they assume that there is no prototype code at all. Also, I agree with you that often you have to rewrite when you move from prototype to the real implementation. Sometimes you can reuse parts of the prototype code, but you must be ready to rewrite. You really have to decide from case to case. Regardless of unit, BDD, ATDD, or other variants many of the difficulties remain Side effects Whether it's mocking, fixtures or functional tests, dependencies on external states or systems are often the source of most complexity in tests, confusion in how to test, and biggest risk in getting it wrong.
A few issues I've seen: Mocking: forget to assert the order of calls Mocking: mock doesn't match real call or response Fixture: test relies on unrealistic data, masking other issues Fixture: test an impossible state in production Functional: false build breaks because of dependent system being temporarily unavailable Functional: speed of test is very slow You will have to change your approach to coding, for some it will be a drastic change. Unit Test specific: large refactors A large or fundamental refactor of a significant codebase with tens of thousands of unit tests will generate a huge cost in order to update all the tests.

Johan Johan 2 2 silver badges 3 3 bronze badges. If you yourself don't understand your own code, how can a handful among billions of possible testcases possibly guard against the code being wrong? Because you understood it when you wrote it but forgot about it along the way? This is where BDD comes in The Overflow Blog. Featured on Meta.
