How much should you practice to make JEE advanced maths and chem a cake walk?

Title hi explain kar raha hai. Please resources ko bhi mention kariyega - jo atleast JEE advanced level ka hai, yaa usse uccha level ka hai. Haa, mai yellow book, pink book, N.Awasthi level 2, MS Chauhan, VK Jaiswal level 2, PYQs ke baare mai janta hun. Isse chhor kar, aap agar koi tougher questions resources jaante hai tho woh bhi mention please kariye. (Maths and chem only).
