CA

Register yourself for CPT exam and prepare well for the same.
All the best.

After completing class 12th, you can appear for CPT exam. After cracking CPT, you can apply for IPCC. There are two groups of IPCC and after passing one group, you can go for articleship for 3 years. After completing both the groups of IPCC and 3 years of articleship, you can appear for CA final.

Practice is the most important part of your preparation and it should be given 100% focus. Once you have completed your revision, you can take mock test. Mock test helps in preparing you for exam and also highlight your weak areas.

If you want to do CA, you should go with B.Com is much better. But if you want to go along with you BBA, you should have at least 60% marks in your degree to take admission in IPCC.

Both are good, but MBA gives you opportunities in all streams and CA is restricted to financial industry.
MBA provides with great management and communication skills which CA course lacks.

Hi,
Iit is good that you are considering event management as sometimes we understand our potential only after a while and not immediately. So, your knowledge of CA will be useful if in future you plan to open your own event management firm and will be good enough to handle the accounts and finance of your company. But, stick to your choice and do not change it frequently as after few years you will be competing with your juniors only.

Yes, you can go for CA, but you might find it difficult because you haven't studied accounts in BBA.
