CA

As a Chartered Accountant CA with 3 years of experience in taxation, you may want to consider pursuing further education or certifications to expand your knowledge and skills in the field. Here are some courses and certifications that you may find relevant:
Certified Financial Planner CFP This certification programme covers various aspects of personal financial planning, including investment planning, tax planning, retirement planning, and estate planning. Certified Information Systems Auditor (CISA): This certification programme focuses on information systems auditing, control, and security. As technology continues to play an increasingly important role in business and finance, knowledge of information systems auditing and security can be a valuable asset. Diploma in International Taxation: This Diploma programme focuses on international taxation issues, such as cross-border transactions, transfer pricing, and tax treaties. This can be particularly useful if you work for a multinational company or deal with clients with international operations. Diploma in Goods and Services Tax (GST): This Diploma programme focuses specifically on India's GST system and covers various aspects of GST compliance, planning, and litigation. Certificate Course on Concurrent Audit of Banks: This course is designed for chartered accountants who wish to perform concurrent audits of banks. The course covers various aspects of bank audits, including the role of concurrent auditors, audit planning, and reporting. Certified Public Accountant CPA The CPA designation is a globally recognised certification in accounting and finance. While the requirements to obtain a CPA may vary by country, the certification typically covers various aspects of accounting, auditing, taxation, and business strategy.

As far as I know, the Bar Council of India (BCI) has not imposed any restrictions on pursuing CA along with LL.B. However, it is important to note that both LL.B. And CA are professional courses that require a significant amount of time and effort, and it may be challenging to pursue both at the same time. It is advisable to manage your time effectively and prioritize your studies accordingly. Additionally, it is important to comply with the attendance requirements of your LL.B. Programme as per the rules of your university, as well as the guidelines of the Institute of Chartered Accountants of India (ICAI) regarding attending classes and taking exams. It is always better to clarify any doubts or concerns regarding pursuing both courses simultaneously with your university and ICAI to avoid any issues in the future.

ICAI has its own study mate for different levels of exams. Once you register yourself with the icai they will provide you the details to login into to their portal & from there you can order book using coupon. Books are free once you register with icai but if you want to prefer additional books then here are some names. Mercantile Law by MC Kucchal and Vivek Kucchal
