Need help in DSA virtual training

Hi all,

I am data engineer of 4yrs of exp. I have been thinking of learning DSA but whenever I start to study I get so confused and get stuck and then leave it behind without learning anything till now. I feel like any virtual online training will help me give a proper plan and will help to resolve my doubts as well.

Please suggest best DSA online virtual training which has lots of weekly/daily assessments to grind me.
