ApplicantLab is definitely geared specifically towards MBA programs but lot of the advice could be applicable to management related programs - it really depends on what your applications include.
If they're "MBA type" and ask for a resume, Statement of Purpose, and leadership essays, then ApplicantLab can definitely help you with this.
You'll find advice on how to respond to all of the most common types of essay questions in the "General MBA advice" that will start showing up in the Writing Modules when you get to them (there will be the option to add this to your account when you get to the "my schools" section).
Our free trial will help you determine how "applicable" things are to you. Upgrading to check everything out in detail comes at no risk - we'll happily refund you within 7 days if you decide this isn't the right fit for you.
