Need help learning pseudocode (for school)

Hii guys, Im in lower six doing Computer Science as one of my subjects but struggle with coding in pseudocode and understanding coding in general - my school introduction was crappy and my teacher was learning with us so my base is shaky, I learnt enough to write my O'level exam but thats it. Does any one have any tips/websites/apps I can use to learn with because I really do want to just don't know where to start. I have researched but cant find any in pseudocode specifically and that aline with my Cambridge syllabus.
