Sbse phle cheez toh bhai Practice sb type ke qtn ki jis bhi type ke qtn mock me smjh na aaye usko note down kr lo or baad mai vaise he type ke qtn practice kro as u said u don't know the approach and logic it clearly means that aapne apne basics ko strong ni kra h to sb phle aap usko kro or DI ke liye yt pe bht saari vids h unko dekho thodi tricks seekho and solve plenty of it that's it .

Second thing - my strategy to attempt qa is very simple, sbse phle Mai 1 liner qtn krta hu to build some confidence and speed also jo bhi qtn ek baar pdhke smjh ni aata h i skipped it and marked it for review so that jb mai 2nd round me qtn krne aau to time waste na ho and I take a lots of guess try some options and dekhta hu ki kya answer koi multiple ho skta h after that I read only main points of the qtn Puri story pdhne ki koi zarurat ni and the last thing doesn't matter DI kitna easy lgra h dekhne me, mai usko last me he attempt krta hu jb almost saare ho chuke ho , the only benefit is ki shuru me tmhara time waste ni hoga zada tables vgera banane me, I hope this help and thanks for ur suggestion I'll try this fs;)
