Please don't get caught up in increasing your "Solved Problems" count.
I've read countless stories of some people having 500 - 700+ problems solved and still failing interviews. (I know luck plays a part but come on, 700?)

My advice is to take a break every so often from doing new questions and focus on revisiting a lot of questions you've done in the past.

Go to the main page and set your "status" to "Solved", if you cannot do the MAJORITY of the solved questions you've solved in the past, then you don't need to be doing new questions right now. You're only increasing your count, but not retaining the patterns you've learned.

Keep grinding. Be Blessed.
