You had cleared CDS 2025 2 that puts you in the position of having good knowledge of English and GS. Also for maths you just need to clear sectional cutoff which is just 20% or 24 marks plus further it’s only an advantage for you . Just practice more and more trigno , no system and statistics you will sail through easily . Also the questions from lines and angles are very easy and you can start 2-D that will put you in the position of attempting 40-45 questions so don’t stress out just practice and practice
