You should note that Angular doesn't need full commitment. Many people think that they should use Angular only if they are building Single Page Apps. But it's not true. You can use as little or as many features as you need from Angular.
For example, in your case you will deal with client side validation, DOM manipulation and AJAX requests. All these can be hugely simplified with the help of Angular. If you use Angular correctly, you won't probably need jQuery to do complex DOM manipulations. It will also be easier for you to do form validations with the help of Angular's form validation APIs. And you can nicely package your API calls inside services/factories (or use ngResource?).
So, if you are learning Angular and enjoying it, feel free to use it in your next project.
