You must choose biotechnology as it is a noble and respectful career and will offer a better salaried job. Thus, it is better and you should go for it.

B.Ed and MCA are two different courses with different subjects.

Sana,
PHP is a good option and also most of the local companies in Pune work on PHP. This is my personal experience because every company in which I gave the interview works on PHP. Some of the MNCs also work on PHP.
PHP is easy too.
Can you tell me about your educational qualification?

Hello,
Both the fields are very different and before choosing one you should to know your strengths and skills.
Web development means all the front end coding
so if you have good knowledge of languages like PHP, asp, Java then you should go with web development.
For web designing, you must have knowledge of designing language like ajax, HTML, css, bootstrap etc.
As per my view, web development is very good option because there is very good scope after it and also you will get a good package as compared to a designer.

M.Sc in IT is a very good option after BCA, but it will benefit you if you have good knowledge of programming. M.Sc in IT is a practical course, and here you are talking about distance education. By doing this you may be able to get a degree, but may not get much of knowledge, so after M.Sc there is a possibility that you have to do some certification course to get a job.
While thinking about distance learning, I think that MBA in IT is more beneficial as compared to M.Sc IT.
