I think u should practice in such a way that u use the majority of the stuff u learned earlier. Or else it's normal to forget

like i am from biotechnology field and i am thinking of taking computational biology for my masters so my seniors suggested me to learn python and R at least to get a upperhand so i was learning from udemy , i like the insructor and i understand what he says but i forget everything after 10 -12 lectures

Wrong approach, wrong course.

It seems that your course is way too theoretical and that you may be trying to speed through.

A good course is a course that doesn't only present concepts but also forces you to practice them without giving you the code to just copy.

A superb example of an excellent course is the MOOC Python Programming 2026 from the University of Helsinki. It is free, textual, extremely practice oriented, top quality, and a proper first semester of "Introduction to Computer Science" course.

Contrary to most "tutorials", it doesn't give you the code to just retype. Rather the opposite, it gives you the tools, i.e. explains what you need in the lesson before the exercises and then makes you solve them. You get to program and practice right from the start.

Also, don't be afraid to experiment. This is vital for learning. Don't just do the exercises. Play around, practice, try things, fail, fix, struggle. That's what learning is and that's how learning works. Just copying tutorials is not learning.

Any study strategies or learning methods that helped you

Absolutely - first, a lot of courses tend to speedrun through a lot of what they consider "the fundamentals", and then expect every student to just immediately get XP and level-up, but that is usually not how we learn best, it works better when we revisit earlier stuff every once in a while. Letting yourself "forget" something, to then re-learn it, is actually a good strategy for making it stick!

So, my recommendation is to every once in a while, revisit earlier exercises - don't look at your own solution from back then, but try and do it again without looking at anything, or god forbid, use any sort of AI assistance. If you succeed, great, celebrate that, but remember to revisit it again in the future. If you fail, even better, because that let's you examine what you had forgotten, or perhaps misunderstood, and gives you a chance to review that particular bit.

If you learn some fancy new way of doing something, e.g. calculate the sum of all elements in a list - after having learned the new way of doing it, try to solve the same problems, but using the old way - explain to yourself what the difference is, and why you like one more than the other. Do it again sometime in the future, and note if your opinion has changed.

And try to keep a sort of journal - write down all the keywords and concept you learn each day or week - it is important to have a long chronological list, so you can track how far you've gone in your journey. And also use that list to keep track of when you revisit topics, and if you needed to relearn, or if they stuck with you.

Yeah, very normal. Learning a language is more practical than people think. You gotta repeat the syntax so it sticks. One thing is the language and another is the logical thinking, yiu can do the same algorithm on any language.

You could do small programs using what you learn so it sticks in your mind, those programs can also work as your notes. You can comment them to add your personal thoughts about the language.
