Depth of processing sounds a bit similar to multi-sensory processing. It may be difficult to use depth of processing techniques but multi-sensory processing is much easier. In multi-sensory processing, you work with the subject matter with visual, auditory and tactile senses. This means, you see the information, hear the information and touch the information. This is part of the reason behind note taking. It takes auditory information and adds tactile processing.

For you, when you are in a lecture, note taking will be important. If you are reading a text, it will help to read any information needing memorization out loud then write it down.

The point is to create multiple memory streams or pathways.

So, the challenge for you is to 'learn how to learn.' Your school's disabilities department may be helpful if you find yourself struggling. Don't be too proud to ask for help there.

My best to you.
