Dear Student,

Okay, you have made a really strange and challenging decision. The topics, difficulty level, and subjects are completely dissimilar. It is equivalent to taking two streams of study. But if you've decided to do it, I have faith that you can.

You will undoubtedly gain more understanding of Physics as your B.tech degree progresses. The issue will be with chemistry and biology.

You are a dropper, therefore you are aware of the material that needs to be studied. If you devote 3 days per chapter to Biology (using NCERT, coaching materials, and multiple-choice questions), you can finish the subject in 4 months. Make your own notes for chemistry, and for physics, create a formula list.

Straightforwardly speaking, your consistency and sincerity towards your primary AIM must not change. You can demonstrate this by devoting nearly all of your time to your preparation rather than giving the task that is less important to you much attention. (At a minimum, maintain a 95:5 ratio.)

Hope this helps,

All the best!
