"Learning openings" has its limitations.

If you are considering learning new openings, read this opening before you buy a new chessable course.

I love studying openings. It can help you to know more ideas and understand new secrets about chess.

However, don't try new openings if you don't understand why you lost most of your games.

Improving at chess requires some level of self analysis and paying attention to your natural patterns/tendencies.

To improve, most people don't need to learn new openings; they need to improve their overall technique: convert winning positions, defend losing positions, and find the right tactics at the right time. 

If you are currently working on that, then opening study will be an excellent complement to your study and very fun; if not, you will learn new things but make the same mistakes (but in a different opening).

If you want to save time, focus on getting the proper technique first (fundamentals).

Hope this helps.
