This year the MHTCET 2021 is reduced but its not said anywhere that it will be applied for 2022 also. As a result I would recommend you to prepare the whole syllabus for MHTCET 2022 and focus more on the reduced syllabus but don't leave the other parts. If at the last moment, the syllabus is made to be the full syllabus then you will not face any problem as well as if the syllabus is reduced then also you will prepared. So this can be the ideal strategy for you to follow to have better chances.
