HI Vitto,

The 5 answer choices to DS questions are always the same 5 answers (and in that order). While the wording of the 5 answers might appear to be complex, each defines a specific set of results. Once you've done more practice and you're comfortable with the logic behind each of the 5 choices, then selecting the proper one will be a bit easier.

If you're referring to the explanations behind each of the DS questions in the OG, then it's worth noting that sometimes the "math" approach to solving a problem can be quite complicated. DS questions offer a certain degree of flexibility to the Test Taker though; sometimes the easiest way to correctly solve a DS question is to prove that a pattern exists in the data (by TESTing Values or knowing Number Properties, for example).

Keep practicing though and make sure that you take lots of notes when you do your work. This will help you to hone your skills before Test Day.

In reality, i'm doing not too bad on PS but DS is being a nightmare for me. Any tips welcome...

Please know that everyone struggles with Data Sufficiency (DS) questions at first. This question type is totally unique to the GMAT, so it's foreign territory.

If you're looking for some extra DS resources, we have a free set of videos that cover everything you need to know: https://www.gmatprepnow.com/module/gmat-data-sufficiency
