Don't worry about DS. It's really tricky.
Here is what I suggest for DS approach.
There are two main forms of questions: Yes/No question and "Find The Answer" questions.
In the Yes/No questions, you get a statement in the stem, then a question such as "Is x positive?" followed by the statements. The key to this question is that the information in the statement must remain true as you work the problem (such as if Statement 1 says x+y is < 5. you cannot use any other value for x+y that will sum greater than 5) and if you can answer the question Yes, it must be ALWAYS YES or ALWAYS NO for the statement to be sufficient.
The "FIND THE ANSWER" types are a bit easier, in my opinion. You might get a question that says "x + y = z" What is x?
(1) y = 4
(2) z is equal to one half of y.
Here, we have 3 variables, so we need to know at least 2 of them. Only together do we know y & z so then we have enough information to answer the question. The actual answer DOES NOT MATTER, it only matters that we have enough information to answer the question.
If I think of anything else, I'll come back and post. Hope this little bit helps.
Yes I have taken the GMAT Club tests
and have given the first 3 tests and scored 16/37, 15/37 and 19/37 respectively. In DS questions, i tend to get lost with basic concepts..thing which otherwise i would pick it right . I am missing basically how to eliminate or rather how to relate to the stem of the question..perhaps i need more practice and some careful error handling to do when i make a mistake ..
What do you guys suggest to do to pick up on the DS portion
