Let me play with a calculator

By the way, you may want to strategize too here to see how much you need to improve (one of those things we did in college trying to calculate the minimum score needed on a test for a certain grade

)

Since you mostly need to focus on Quant, and if you don’t hate it but embrace it and refresh your quant, I think you would be well within reason with a high starting score you have. However, it is obviously harder to improve at the higher levels (easy to go from 505 to 605 but harder from 605 to 705). I don’t see a reason you could not get there. My only suggestion is to take short brief (10-question) daily quizzes of the material you covered so you can track progress daily and understand if you are improving, hitting goals or if you are just letting the material go past your mind and you are just checking boxes so to speak. Your ability to apply the newly learned material will decide your chances. however, again, I think the chances are higher than 50% you will succeed.
Your timeline is reasonable. 1.5 hours a day of high quality study time and double that on weekends should do it by end of June. DI is a pest and a nag, so that’s the only wildcard as there are not many strategies to defeat it.
