Obviously there already is some logic in org-drill.org to handle latex
fragments.  See the lines containing (org-preview-latex-fragment).
Looks like the logic for displaying the fragments is somehow broken.

A pragmatic patch to keep you going with physics drills could be to
comment out all those lines containing (org-preview-latex-fragment) in
org-drill.org.


HTH,  Marco
