There are several factors that go into what grade you get. While I do believe intelligence is one of them, that changes over time. "Intelligence" is not stagnant, it's very fluid and changes as you learn new things.
In my experience, the biggest factors are ability, effort and consistency. Do you have the ability? Are you making your best effort? Are you consistent in your efforts? Those are the factors I would look at.
Grades are merely a snapshot in time. They are dependent on a variety of outside factors: everything from the mood the student is in at the time of the test, to the amount of sleep from the night before; likewise it could have a bearing as to the mood of the instructor, to how many stressors were affecting the instructor at the time the test was created. So, do they prove intelligence? Not in-so-much as might be thought by a single test.
That being said... guess what? They are about the best tangible indicator available. But they work best when viewed over a period of time. They can show trends. So are they a "reflection" of intelligence (which was really the question asked)? Yes.
But just like a reflection viewed in a mirror, it could be blurred or obscured by how clean the mirror is (or how much bias was put into the tests which generated the grades).
The trick is to realize any time you are viewing a reflection, it's not the real thing. A solid educator looks beyond grades when rating a student's intelligence.
Not necessarily, although a low IQ will diminish your ability to understand. I agree with much what's already been said.
I was (according to my records) very intelligent when young but could never unlock it so was only ever mediocre at school. There are several factors that can act against learning at school, for example:
Lack of interest.*
Actual inability or slowness to understand - perhaps a different approach to the subject would work but that is not necessarily offered.*
Teacher's poor performance.*
Pressure from parents or others to "do well" - either by rebellion or stress - rather than help and encouragement.
Similar pressure in direction.
The opposite - no support from, or even hostility to, learning, by parents or other elders.
Stress from other causes like the attempt to "succeed" or being bullied.
*These were my main factors. Of inability to understand, I finally learnt certain maths subjects only by chipping away at the, many years later, in my own time and way.
I agree here as well.
No. Grades reflect work effort on a specific task. They reflect intelligence only as much as the person doing it chooses to bring to bear on the subject. If you don't like the subject or are bored or acting out or have no aptitude., grades will be low
No, they are not necessarily a measure of intelligence. Look up Howard Gardner's book Multiple Intelligence and Education. There are different sorts of intelligence and grades are not necessarily a measure of that.
Here is a good link for anyone interested http://www.infed.org/thinkers/gardner.htm
Depends on what intelligence you are talking about..there are different types. If its an English exam, it will tell you how good you are at English. Not Physics. Not Maths.
Also, it won't reflect your emotional intelligence, your social intelligence. So...not really.
it is pure crap...most of my teachers should have just phoned it in...most iq tests are bogus also...they are knowledge tests and not intelligence tests...i am tired of people who are not bright at all running everything (except Obama, he really is smart). our entire system of living is wrong...
imho....not at all.
Not much. They might be a good reflection of how well you can play the system though.
I believe they are a reflection of your ability to sit exams and to remember facts. That's not necessarily the same thing as intelligence.
To a point
Either intelligence or effort
Dumb people usually don't get A's.
