Hello ,

Greetings! 

It's good that you are interested in Maths, let me first tell you that  Standard-Level and Basic-level Question papers shall be based on the same syllabus. However the Standard-Level Mathematics assesses higher Mathematical abilities compared to Basic-Level. Accordingly, the difficulty level of the Mathematics – ‘Basic’ is less than that of Mathematics-‘Standard’.

Mathematics-Standard is to be passed at class X, for taking up Mathematics at Sr. Secondary level so if you want to take maths in class 11 and 12 then you should go for standard maths .

thankyou
