@yousefk, congrats on going from 1880 to 2350! That’s not easy, but it means you’ve reviewed properly. Believe it or not, it’s a rare skill to know how to improve from practice tests. The point I’m trying to make is taking practice tests alone is not the way to go. You have to pair it with proper review.
To be clear, practice tests are definitely important. They have a time and a place. However, simply taking a test, then going over the questions you missed rarely leads to any significant improvement. Most people don’t actually go over questions they missed the right way.
Proper review involves:
- identifying problem/concept types you’re missing
- mastering every variation of that concept at the proper difficulty levels
The problem with only reviewing the questions you missed is that you’re never going to see that exact question again. Moreover, that one question doesn’t contain different variations of the same concept.
For example, if you got a 30-60-90 degree triangle question wrong and figure it out afterwards, that doesn’t mean you’ve mastered the 30-60-90 concept entirely. It just means you’ve learned how to do one variation of that concept. On the next practice test, you could get another 30-60-90 degree triangle question wrong because it’s asked in a different way, or the circumstances are a little bit different.
This is where prep books or programs come into play. You should go to the chapter that deals with that concept and learn every variation of it.
You said the SAT doesn’t test for a deeper understanding, but it does. Just look at functions. There are easy function questions, and there are very hard function questions. Functions are one of the most common concepts on the current SAT, so the test can afford to test that concept in various ways across multiple questions. Just because you can solve “If f(x) = 2x, what is f(5)?” doesn’t mean you can solve “If f(x) = 2x - 4, and f§ = 10, what is the value of p?” Or what about graph functions and symbol functions?
You’re right that there’s only so many ways the SAT will test a particular concept, but you have to expose yourself to all those variations and difficulty levels. Taking 10 or 15 tests is one way to gain that wide exposure, but it’s too unorganized and time-consuming.
Not only would you be trying to learn too many other concepts simultaneously, you’re also waiting to take 10+ tests before you would come across all the possible variations of a particular concept. It’s more effective to decide you’re going to master 5 concepts than try to superficially learn 20 things.
Another funny thing I’ve noticed is that many students will often miss the same EXACT variation of a concept on the next test. In fact, they could very well miss the exact same question. You can literally show them the same question they missed before, and they’ll have no idea how to approach it even a few hours later.
This happens because many students never go back to their missed questions more than once. Their idea of review is passively watching a video or reading an explanation. Once the explanation makes sense, they believe that’s all they have to do. They believe they’ve mastered it now. The problem is they didn’t actually work through the steps themselves until the concepts are ingrained in their heads.
You’re right that the weight loss analogy is a bit flawed, but no analogy is perfect. I’m using it to illustrate a point – not every factor has to be consistent for an analogy to be useful. Taking practice tests may lead to test format familiarity, develop endurance, and maybe even give a sense of pacing, but those factors are trivial compared to actually knowing the material. One big reason people are unable to finish or pace themselves properly is that they take too long doing the questions. Becoming more fluent in those concepts automatically increases speed.
Learning the concepts is the heart of prep – the true dieting and exercising.
I’m not saying don’t take practice tests. I’m saying don’t ONLY take practice tests. More importantly, you have to REVIEW the practice tests properly.
