I was just looking at your both ESR, in both the test your score in verbal is almost the same.
(Comparison in Percentile)
Critical Reasoning:
You scored well in your Test 1 with 76% but in Test 2 your score decreased to 55th and if you look the subsection of CR in Test 1 your critical skill were good but in Test 2 it was not so good.
Reading Comprehension: In Test 2 you have improved a lot in RC as compared to Test 1.
Sentence Correction: I think this is the area you have not improved a lot , means your score is consistent in both the test.
In both the Test you score in Quarter 2 is very less, the question of Level 700 comes into this quarter. You need to improve your skill in Mid quarter.
Overall: You have improved in RC but you have not practiced well in CR and SC. You can score well in SC, because this is the area where you can improve your verbal score. Your CR skills in Weaken, strengthen and assumption questions need to be improved, try to read slow in these type of questions and paraphrase the argument in your own words.
In both the cases just download the
Error Log of Gmatclub and look into the errors you have made. Note down those errors and read it twice or thrice. Then again practice it. I am sure you will improve it
Quant: You have made mistakes in Mid and Last quarter. You have improved in probability, Permutations and combinations and sets but you degraded your score in other sections. I would say that you have good knowledge in quant but You just need to practice well. Try to practice again with Gmat club quant test. This time give a test in more organised way. Take some notes while answering the question, use answer options to solve the question quickly. I think you are making some silly mistakes in quant. Try to improve those silly mistakes.
Do not rush the answer in the end because in the end many questions are easy. Try to skip some questions in the mid. Try to find that in which section you are not good then try to make some logical guess in those questions. For example, in rates and work questions are quite long to read so it will take more than 2 minutes to solve. I would say if you are taking more time in some questions in the mid quarter try to skip, but do not make guess at the end.
Need any more help, Let me know.
