Hello rikinmathur,
A score of 690 is decent and tells the entire story about how well prepared you are and how to change the gear now to meet the target score of 750+.
With my GMAT tutoring, guidance, and counseling experience, we have to accept a fact with a pinch of salt that diagnostic/ mock test scores are above then what one should expect in a real test. There is often dropping in the score. Some students have even experienced a drop of 100 pointers. It is one of the realities, and your preparation should not sideline this fact.
You can schedule a Free counseling session for 20 mins with one of our experts:

A couple of things that can be a noticeable barrier to your scores would be some or all of the below.
• No expert support (maybe) who can tutor, analyze, and guide you during your learning especially on hard-level questions while stably hitting middle-level questions.
• Not well aligned with time to solve questions.
Since we are a math expert, we will recommend you go through our post on the GMAT club: Breakdown of GMAT math questions and types:

We recommend that you must learn the Variable Approach for solving DS questions and the IVY approach for solving PS questions in order to improve your accuracy and save time while solving the question types.
