I'm going to take an IT Course in my College but I am graduated studying in STEM strand what basic topics should I review first to cope up in taking up IT.
Hey there, congratulation on your achievements. Coming to your question, it's very risky to guide or to give career advise without knowing anyone much. But since your main plan is to get into IT and since you have tagged "html", I would recommend you to start with Web development itself, okay, why?. Because Web development is a field which will make you love IT and also at the same time you'll grow exponentially fast and later you can dive into much advanced field which is most probably AI or machine learning or even game development. Having said that and assuming that you are beginner just like most of us, I would recommend you to learn html, CSS and JS but ofcourse with some small basic projects side by side. Good news is that you can easily switch between fields if suppose you don't like it and this is the beauty of Computer Science or IT. You can also give some of your time on learning basic computer theory which is easily available on the net either free or paid one. All the best! :)
Thanks bro! Already studying java
Another reason why I've recommend you to learn Web development as you debut into IT is because in Web development you will have finished projects quite fast and its not that tough, which is quite motivation and addictive indeed, reasons - Web development community is huge and you can get help easily. But don't believe me completely try to experience yourself and seek helps from those more advanced developers.
Mark Joshua C. Sayen Yeah, good choice, you won't regret. Anyway, happy learning and all the best!
