As randogogogo hints at, it's not necessarily the case that you are demonstrating skill at the appropriate level. If you take the question 3x + 1 = 10 And solve it (for example) by trialling x=1, x=2 and x=3, then you are able to answer the question correctly. You may even be able to answer a set of questions correctly. But, you have not learned the relevant algebra skill to be able to generalise this process.
