Hey aspirant

The VITEEE comprises of 125 Multiple Choice Questions with 35 questions each for Physics and Chemistry, 40 questions of Biology/ Mathematics, 5 questions of English and 10 questions of general aptitude.

So you should begin with Mathematics abd physics with more focus because both require extra hard practice (in general) and then devote the time to chemistry.
