Hello dear student,
Greetings!
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.
To continue Mathematics as a subject in class XI/XII and further, Mathematics-Standard is to be passed at class X.
But when we talk about medical science stream then you have to study only Physics,  Chemistry and Biology.
I mean Maths isn't there .
So , if you take biology in class 11 and 12 and want to go in medical sector , do mbbs etc , you can freely choose basic Maths .
thankyou
