UPSc with MSc Chemistry

I am starting my UPSC preparation also I have taken admission in MSc Chemistry. Will I be able to manage UPSC mainly with MSc Chemistry? I am a beginner and want to give 2028 attempt having no knowledge about how both upsc and msc are going to work in these two years.

Suggest me a good strategy to prepare while also scoring good in MSc. Feeling low at motivation and feared about this so much..
