SC Strategy

There will usually be a choice split in the ratio of 3:2 or 2:2:1 in the options for SC questions

For example:

Since 1966, roughly 21 percent of those enlisted in the USMC had reached an E-5 ranking in fewer than three years.

(A) had reached an E-5 ranking in fewer than three years
(B) have reached an E-5 ranking in less than three years
(C) have reached an E-5 ranking in under three years
(D) had reached an E-5 ranking in less than three years
(E) have reached an E-5 ranking in fewer than three years

You can see 3 haves: 2 hads. When you eliminate had, you can directly remove options A and D at one go.Now, it boils down to B,C and E, of which you can clearly opt for B as it makes the most sense!

There are cases when a 3:2 or 2:2:1 split is not possible. But, usually, you will find a split. This technique helps saving time as you can eliminate choices at one go and you can answer more accurately.
