I am a 1st year Computer Engineering student in what people would call a tier 3 college. I have intro to c as a subject in first semn I want to start learning it online, through youtube or some couse like NPTEL. I have a few questions,

1. Should I learn c and other languages they will teach in future from only the college lectures or is learning it from youtube or some course alongside with college lectures a better option?
2. Is there any language that i should learn before/alongside with c?
3. Any channel or couse reccomendation, I have heard about 'code with Harry' and NPTEL course.
4. Any skills, be it communation and team leading or field related that i should start developing from 1st year itself?
5. What should i be doing to have myself a cut above other ce students? as there is lot of competetion nowadays
6. Any general tips for my upcoming 4 years of college.

If you find my post irrelevant, just tell me and I will remove it. Thanks,
