Maths Spl

Yes, it's compulsory to have Maths in class 12th for B.Com (Hons) in SRCC.

Hello Abhinash,
Unfortunately, you are not eligible for B.Com Honours at BHU.

Hello Ajith,
That is only you can answer, of whichever interests you. In my opinion, if you are a techie then go for MCA.
If you are management oriented or business person, then go for MBA.
If you are creative, then go for fashion designing.
Good luck. Choose wisely.

In PCM, there are a lot of courses available but the best course is engineering if you qualify JEE Mains/Advanced examination which held in the 1st week of April every year. After counselling of JEE Mains, if you get any IIT, NIT, IIIT, or any reputed government college then go for engineering. If you don't get one of these colleges then prefer B.Sc in computer science or mathematics.

Maths is very important in commerce but also in various other fields also, so do not take it as a casual subject, it is very important.

Unfortunately, since you have done B.Tech in Instrumentation and control engineering, you do not qualify. You need to be a B.Sc in mathematics and computer education, or any other degree that has math and or computer education. But, you can do it now. So, do it if you really want to get into M.Sc Mathematics, and are passionate about it. Another advantage would be that you will be a double graduate.

If you are not good in mathematics, then there is no problem, but you should improve some topic of mathematics, like integration differentiation, trignomatery. Because, it is very useful in every subject.

Sorry, but don't think you will get a government college, but you can try some other university examination.
