In need to of full versions of softwares oriented for electronics engineering as i'm on job search

i'm electronics engineering graduate but have been working in a different sector for few years. i quit my job and am planning to work in my domain 1e. electronics engineering. so i need full versions of softwares to practice my skills and do projects.

kindly help me out withwebsite links where i can download and install full versions of softwares like matlab, python, C/C++, Embedded C/C++, altium, cadsoft, keil, xilinx and other electronics related softwares if anything new is running on trend now too.

if its cr@cked also, its better. because i saw for matlab they have basic features or as a trial pack for a month. so a full version will be better in this case.

Thank you, I'm counting on you guys.

i've no idea about softwares, as i'm not in the sector for sometime.
