I want to pursue ca couse

Yes, you can pursue CA Course. Even the study materials for all ca levels are there in Students Menu Bos Option. As of now, you have to appear for CPT entrance test exam to do CA.  But there is a proposal before government for exempting graduates from appearing CPT, for which the approval is pending. Hope it comes in a month or two.

If you are non-commerce graduate, then it is advisable to go through CPT level. You can still do job along with study. But after passing IPCC 1st group (as per existing rules) you have to join 3-years practical training under a practising CA/Firm. At that time, you may be required to resign from your job. Further details can be read from below link.
