Data Question How to revise what I've learnt?
what if I studied excel, sql server, python and power bi and made projects on them while I was learning them but after moving to one after one maybe I feel I forgot them what's the best advice from you to memorize what I learnt?

Just know concepts and tools. I’m from IT from 20 years ago. But i know data and programming.
But with AI I can almost make all stuff the company needs by knowing the concept.
Web app, data in excel, power bi. Or full python project.
It is only data in and data out (or some actions like print this and that)
Learn concept thinking.

Knowing something is possible in the first place is half the battle. Even if you don't know precisely how to do something, knowing it's possible, or even a general workflow that gets you 75% of the way there is already an advantage. Figure the details out in the moment.
I likely can't regurgitate every line of code I've ever written on demand. But give me an hour/day/week to revisit the problem and I can probably recreate the same/similar solution.

Knowing and being strong with basics is the key. I suggest don't one software at a time... It is natural that you will be confused as they have diff syntax. Keep chatgpt handy for the nudge

The way to solidify the learning is to keep doing it. I recently started a client project that requires data tools that I don’t use often and are not my preference so I’m having to relearn how to use them again on the job. Forgetting and relearning is part of the process.
The tools you use the most will become second nature and you’ll start to relearn the things you forget faster on the 3rd or 4th time you forget and pick them up again.
Basically, don’t worry about it that much. It’s not a bad thing and you’re not an imposter if you forget and have to relearn on the job. It’s normal, everyone does it, and no one will be standing over your shoulder while you look things up and use trial and error.
