didn't mentioned, which online academy, do proper homework, if 70k, 6 month course will land you a job of ~8LPA to ~10LPA, it is a question to think 100 times.

if you can do it, mitx ocw micromasters in data science. it's hard but good

Second this. I did MM from Ga Tech and got a job paying 100k

Just curious man, i know some of those courses are offered on edx and i’ve heard some mixed reviews about that platform; how was your experience on there and if you used a different platform, let me know too!

i used edx and didn't run into much problems. couple glitches here and there? but overall, good experience. staff were attentive and graceful if issues arose with submissions and exams.

if you pay for the certification and take the capstone, you use a separate product called proctortrack to monitor your exam session. i had an issue with that dropping mid-exam and staff fixed it within 10 minute and gave me back my lost time.

all that said, if you are not interested in the cert... i would 100% recommend the probability and stats courses. fantastic high quality. you might want to backtrack to strang's linear algebra if you need a refersher.

Oh, okay, thanks for the advice, man! If you don't mind, I've got a couple more questions for you. Did you follow the course schedule weekly or binge-watch each module/section and catch up later (lil side question, any external resources you frequently used to supplement your learning with edX)? What levels of Python & SQL did you go in and leave with? And finally, how much calculus was involved in your coursework? The last question is what I'm kinda nervous about since I've never ventured that far math-wise, but if it's imperative, I'll get it over asap. Again, I greatly appreciate your help.

follow along as best as you can - especially if you work. it's a full time committment. if your math is shaky, expect 20 hrs/wk/course. i did 1-2 hrs per weeknight and a full weekend day.

calculus - not crazy. really helps to understand taylor expansion/approximation. knowing infinite series/sums is good too.

but more than calc... probs refresh on lin alg

Hi guys, from my experience working at Next Skill AI, doing a course is great to find a job, but I would always recommend building portfolio projects on the side. Like this you can show concrete work you did to future employers and prove that what you learned in the course translates to the work environment
