How to prepare for PST & Isl

I’ll be appearing in the oct/nov 26 session and im completely lost on how to prepare for pst and isl. How should i manage to study islamiyat, history and geography at the same time? how should i divide the time and days for each of these subjects and how can i perfect my prep as I still got lots of time? My Urdu vocabulary is really really weak too so I need practice for it too 🙏
