CA

Hello Ram,
There are lots of courses which you can do after B.Com, it is just that opt for a course in the field which incites you. Courses like:-
1) Digital marketing
2) MBA
(and then take the exam of the specialized officers in banks).
3) M.Com
4) Law
5) Forensic accounting
6) Photography
7) Psychology
8) Animation
9) Interior designing
10) Journalism
One more thing I would like to suggest you is that do an internship while doing any course so that your efficiency will increase and even you can earn while learning and getting work experience.
Moreover, don't think about salary. Salary will depend only upon your efficiency. Just after finishing your course you may get more than INR 40,000 provided you are that much capable and efficient.
At the end, think twice before you choose any course that too in terms of your interest and not money.
All the best.
Please feel free to revert.

Distraction - This is a very basic challenge which people find when they appear for CA exams. With a number of distraction options in the society and social network, this will be a big challenge.
Fatigue - CA syllabus is voluminous in nature, this makes people get fatigue easily. Although people sit with books, topics might not be moving fast. This will be a major problem. According to me, it's easy to remove this challenge. While you start your preparation, be slow (make it 3 to 4 hours a day ) slowly increase the hours as days progress.
Comparison - this problem will be there for anyone who discusses CA preparation with friends. How many did you complete? What have you completed? These discussions increase your stress factor and disturb you mentally. Avoid it. Every one of us has their own speed, who finishes topic first is not a matter of evaluation.

Just after the results are out, it would be the best days of your life because that happiness of clearing the toughest exams in India and across the world is superb.
But after that, things will definitely get tough because then the confusion comes, you don't know what to do, Which type of profile to go for? To go in the industry or to go for practice?
Right from preparing for the exam to your preparing of CV to sending and applying for the right companies, if you are lucky, you might get your desired job. But, if you are, it can get very frustrating - giving interviews, following up, finding contacts, facing rejections, etc.
You are going to spend at least one-third of your time at work so no matter what, you have to try and make it a good time. That is why sometimes it's actually the decision before getting the job which becomes very important.

When I read the question, the instant answer that came to my mind is CA. No doubt that CA is far more advanced and acceptable in any industry. CWA and CS have comparatively fewer opportunities.
If you are doing CA then you should complete it within 4 years. Not more than that to achieve everything on time otherwise your life will be tough if you started getting flunked.
Start working with studies instantly. Work is a very important part of CA, without working, you can't get the true meaning of CA.
I will not write much about CWA and CS because the scope of both the courses is very limited as compared to CA. CWA takes around 3-years but the syllabus has been changed now and also it has a very low passing percentage. So it will not be easy to clear CWA either but its return in terms of package can't surpass CA. You can get a job in foreign countries with CA. This benefit is not available with courses like CWA and CS.

Yes, your marks and your attempt get counted everywhere you apply. If you are looking for a job in an MNC then you must have scored good marks and have less number of attempts. If you take many attempts then only it's on company's hand. They can give you the job if only they find some real quality compared to others.
Also, if you can explain why you needed those extra attempts, you still have a chance to shine in the Interview and get that coveted articleship.
Generally, this is used as a distinguished between the quality of a student who has the same scores or experiences. Although this may not be an ideal way, the fact that one student could clear the same exam in the first go deserves some amount of preference.
This consideration is only done in the 1st or 2nd job but as you move up the ladder for the work experience, there will be many other skills that you will acquire which will boost your overall profile.

Here are some of the best coaching for CA:
1. Advance Education Center - Offering tutoring facilities to school, college, post graduate students and coaching for professional courses like CA, CS, CFA and ICWA.
2. Account Age Infotech Pvt. Ltd. - Offers job oriented courses in the field of financial accounting, banking, taxation, VAT, excise and TDS. This coaching institute has good faculty member which helps student to cover the syllabus of CA
3. Vidya Tutorials - Engaged in providing coaching courses for the preparation of CA and computer courses with best faculty member and average good result
4. Marigold Classes - Providing class room and postal coaching courses for the students of chartered accountancy and commerce courses.
5. Sri Sankara Coaching Centre - Offering professional courses like the chartered accountancy, cost accountancy and company secretary. Having a best result in the last few years.

Nothing is tough, CA or CMA almost same in study and it depends upon the capability of the student. Basically CMA gives more emphasis to cost and operations while CA gives equal importance to law, cost, tax, accounts, etc.
So if somebody likes more practical then go with CMA and otherwise go with CA. CMA is more practical then CA.
Foundation- CA has less syllabus with more details but in CMA have more syllabus but details are less.
Intermediate Level- CA have some tough subjects in inter level, but so as CMA consists 8 subjects with one more subject in comparison of CA have 7 subjects. CMA wide syllabus again here in comparison of CA but CA have more detailed syllabus again.
Final Level- In final level we face same number of subjects in both CA and CMA. Here we face same level of toughness in syllabus. In CMA we have choice of choosing one subject as specialization while in CA we have no such choice. So in last final level we can say CA is tough from CMA.
But in job security CA offer more job security from CMA.
And in training period CA have very tough training and whenever you complete you training after that you appearing in final level. In CA you have to complete training of three years after completing CA inter (IPCE). CMA has more flexibility.
So at last I want to say if you want to do CA or CMA then you should ready for hard work and dedicated to your course and syllabus are almost same as 80 to 90%.

The choice purely depends on the ultimate goal that you have set in mind.
Actually, the course content plays a very huge role in deciding the best match with law. CA course although can be a good choice. However, the context of the syllabus is quite different from that of law. The similarity between, both CS and LL.B. is that both of them are law focused courses. The CS curriculum attempts to make you study corporate laws in depth, whereas an LL.B. course will make you study a number of laws ranging from civil to criminal.
If we now consider the fact, that you want to primarily be a CA, and then pursue a degree (CS or LL.B) that is law focused, I would suggest that you would like to practice in corporate law and tax law matters as a Chartered Accountant. If that is true, I would suggest going for LL.B. as an additional degree because a CA or a CS cannot represent his client before the High Court or the Supreme Court. So, in case you grow in your profession and would want to litigate before these courts, you would need a membership of the Bar Council, for which an LL.B. degree is a pre-requisite.
