Happy Sunday Everyone,

I think I am feeling well enough to make this tweet

So I want to share a small win here. I am participating in the Data Analytics Super League organized by @lighthall_co and I want to share that I advanced to level 3 in flying colors

Top of the table😁 ImageImage
The Level 2 challenge was a murder mystery challenge to find who the killer is and we were to solve the challenge using SQL

If you dug deeper you'd find out that there was someone who hired it.

Nothing complex but it was fun, felt like a detective 😊 ImageImage
My submission: drive.google.com/drive/folders/…

If you want to try it out yourself and have fun with SQL, check here

Thank you @lighthall_co and @thenaijacarguy for the challenge

it is getting really interesting and level 3 is not easy
Level one was Excel, level 2 was SQL and Level 3 is Python

Deadline for submission is today so let me go and continue my work

Congrats to everyone who made it to level 3. Let's keep having fun 😁

Thanks to everyone who checked up on me, I am feeling much better now

Love 🩷 and light 💡

Have you been trying to improve your SQL skills but you don’t know the right resources to use

Have you been confused on which SQL resource to use to become very proficient

I’d love to share what I’ve used to learn SQL since I started my data journey last year
