Hello Riya
CA Foundation is the newly introduced national level examination conducted by ICAI as entry-level exam for Chartered Accountancy. It is held twice a year, once in May and once in November. As CA foundation is starting stage toward becoming CA but there is a direct entry scheme where a graduate from any stream can directly apply to CA intermediate , foundation level is exempted.

Hiii dear!!!!! Not at all. If you don't want to take the examination then you can alternatively graduate with b.com. and then you will be eligible to appear for the ca intermediate examinations. But in that case, it will take you 1 year extra to complete the ca course.
