The level of Quant in the Manhattan tests is quite difficult and
I don't think you need to bother so much about the test scores!
Though it is important to understand why the scores are going down.
I would recommend the following steps:
1. Take a GMATPrep test to understand what your current level is.
2. Analyze the tests you have already taken and list all the topics
you are making maximum mistakes in.
Link which you should find beneficial -
This link contains all the important concepts pertaining to the GMAT
3. Once your concepts are clear, work on solving questions in your
problem areas and see the improvement unfold. Every time you make
a mistake, make a note of the takeaway and read this list everyday.
A takeaway could be something as simple as "Consider negative
fractions when dealing with DS problems"
4. Last but not the least, invest in the
GMATClub tests. In my opinion,
there is no better source to improve your skills in Quant. They make
you aware of all the traps and and also help you in understanding the
intricacies of the Quant section in the GMAT.
