Need help analyzing ESR; Scored 100 points lower than expected

Hi - Can someone please help me understand how to improve by analyzing my ESR?

- MGMAT #1 3/6/22 590 (38 Q, 33 V)
- MGMAT #2 4/30/22 620 (43Q, 32V)
- MGMAT #3 5/14/22 610 (41 Q, 33V)
- MGMAT #4 5/22/22 650 (43Q, 36 V)
- OG Practice #2 5/28/22 720 (Q48, 40V)
- Official test 6/11/22 610 (41Q, 34V)

Additional Diagnostic:
- I completed the OG diagnostic for quant and verbal and got the following scores about a week before my exam:

OG quant diagnostic:
1) values, orders, factors 75%
2) Algebra, Equalities, and Inequalities 88%
3) rates, ratios, percents 50%
4) counting, sets, series 88%
5) geometry 75%

Verbal OG diagnostic:
RC 83%, SC 75%, CR 83%

Materials/thoughts:
- Started with TTP but then signed up for a Manhattan Prep course with live instruction.
- Supplemented with OG materials in the last couple of weeks and was doing timed sets of medium/hard questions
-I definitely felt myself get slightly nervous on the first question, but was super shocked by how low my test is
-In my previous tests, i usually scored the lowest on SC and my SC score was significantly better than CR/RC. I'm wondering if I need to brush up on those and just do more quant problems to be more confident on the test
-I definitely take my tests in test-like conditions but i do notice i was a lot more nervous during the real thing for my first time!

Any advice is helpful. Thank you so much! Is retaking the test in 3 weeks practical? Thank you so much!
