How can I pass the CUET test in 30 days?

The CUET isn’t until the end of May, so you have a lot more than 30 days. Break your daily practice into two parts: languages and everything else. The key to the language sections is to read something in two of the languages every single day for constant reading comprehension practice and vocabulary building. Make sure that at least one of the things you read is in English at least four times a week. When you get close to test time, find some sample sentences to correct for grammar practice.

For the “everything else” portion of your studying, start with the STEM subjects. They’re the most detailed, and they don’t change. Chemistry questions will be the most complicated, so focus on the specifics. Physics questions will be the most general, so focus on the concepts. End with the current affairs section for exactly the opposite reason: they want mostly an overview and there’s no point studying events that won’t be tested.

As for logical reasoning, there are plenty of books on this. Just get one that has a workbook section and work your way through it over the course of a week or two. Ask a teacher for a recommendation or even just an older friend who did well on the exam.
