Moving this to the correct forum.
Hi. 7 Months is a serious slug and a long time. I think it is good you are re-evaluating.
I don't think the strategy you are using now is the right one however (not related to the prep company at all). What I mean is that doing questions and then going through
error log, etc, you don't need to do endless questions. You can just look at what your weaknesses are already and confront them.
The whole ESR and accuracy can also be misleading since you may do terribly on the RC, get lower on the score scale, then get served with a super easy SC and the report will say you did awesome on the SC's. You have to dig past the numbers and look at your daily practice. It is not like a test would suddenly be all different.
Anyway, long way to tell you to address issues and weaknesses. This may mean creating notes, writing out material, focusing on a single type of CR (e.g. assumption) until you master it and not moving until you have and changing approaches if you are not able to master it. You have to see what works for you. I have enjoyed CR's because I treated them as puzzles, as a game where it wanted to trick me and I wanted to figure out all of the tricks it had. I would be tricked and get questions wrong but only once. Pretty soon, I was not getting tricked anymore. But it does not mean you have to solve thousands of questions. Ideally you would prep for 3-4 months max.
Finally, I would say that you need to make sure you do a lot of review in Q and V every day. Start your day with review of yesterday's and other material that you may have forgotten. This late in the process, that is also your enemy and probably a dangerous one as you may degrade.
About a tutor - not a bad idea to consult one. Most will not be able to move the needle with just a few weeks however. They will usually meet just once a week and give you lots of things to do on your own since it is not practical to spend a lot more time. Maybe twice if you are in a rush so it won't be terribly expensive (depends on which one you use) but you need to come with specific questions and issues. Coming in and saying "help me" is going to waste a lot of time locating what you need help with. Even saying help me with verbal is too vague and even saying help with SC is too vague. You have to drill down more specifically and the success will depend on your ability to identify actionable problems that you can focus on.
