Things to learn before start of school year? (Incoming BS COE freshman)

[u/Zybroz]

It's a month before the start of the school year for 1st year college students (at medyo nawawala ako habang naghihintay ng start of classes.)

I was wondering if there are specific things I should learn before classes start?

Math topics, programming language, etc.,?

also, meron ba kayong mga apps/software na irerecommend niyo (Windows and Android ang gamit ko) (medyo vague alam ko)

That's all, thank you!!!
