Get your basics right
It is critical to grasp the basics of a programming language to get to the next level. So, spend time on getting the basics right and study them thoroughly. Even if you feel like you know them, practice them over and over.
Write simple algorithms
There is always a simple way to do complex things. Even if you have to write a long algorithm, try writing it in a simple way. The complex algorithms can be used when you are really through the entire course. Practice writing simple algorithms and then combining them to perform functions.
It is a common misconception that learning language and coding has to be performed on the computer and you have to only learn the syntaxes and modules etc. But that is incorrect. You have to give attention to theory too.
Read through the language evolvement and also the theory about the codes and the syntaxes. This in-depth knowledge will provide you with better insights into the course. Thus when you know the background of a particular thing, it is easier to put the thing in use.
Practice a lot
Make this practice fun by assigning tasks to yourself and try achieving the goal. Coding is fun if you know how to be innovative. Replace functions to see if you get the same or different output. This will not only help you score good marks but will really help you when you step out into the coding world professionally.
Never refrain from asking for help when you are stuck somewhere. Plus, there is so much help available online that is absolutely free. Your group of friends can come together making the learning process easy and fun.
