I found a horrible mistake in the Treasure of prepladder, In orthopaedics , CTEV topic has info that Ponsetti's method correct in 6-8 days and not 6-8 weeks. Now I regret taking the Pro plan, I thought Prepladder is so perfect that they don't allow such petty mistakes. To my fellow mates , please don't follow blindly everything in Prepladder. They are thinking about their business first and not our education quality.
Inputs in every website or app/software are done by human beings, and there can't be anything that's done by human intervention and doesn't has any errors. A single mistake in the app can't be a spoiler for your preparation, prepladder always tries to provide the best. And for the business thing, you and me also aren't going to provide free service. Efforts deserves a pay, even if there's 10 wrong information in the app doesn't means we lose in life or wasting money.
