Hello AayanRashid,
A score of 640 on the GMAT test tells the entire story about how well prepared you are for the GMAT official test and how to change the gear now to meet the target score of 720+.
With my GMAT tutoring, guidance, and counseling experience, we have to accept the 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. It is one of the realities, and your preparation should not sideline this fact.
A couple of things that can be a noticeable barrier to your scores would be some or all of the below.
• Inefficiency by using time-consuming Conventional method to tackle DS and PS questions still
• 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.
