That’s absolutely realistic.
In verbal, go for chunking instead of reading the whole long passage. You can also find some GMAT Ninja videos on YT on this topic.
For improving quant, you need to see why was the answer wrong, was it a calculation error, careless mistake, conceptual gap, or whatever reason. Write the reasons why you have done a question wrong on a piece of a piece of paper and try to avoid making that mistake again. Keep revising all wrong points every 6-7 days.
For DI strategies, you can also find some videos on YT.
In DI, you should quickly see through the information given. And then according to the question go to that information only that is used to answer the question, this can save a lot of time especially on MSR.
Good Luck!
