Which one of the following are tips to study more efficiently ? A . Maintain a study area and take naps B. Vary activites and reward yourself C. Keep a to do list and multi task D . Keep careful notes to avoid asking questions or emailing an instructor

Respuesta :

A bit of B and D but if you have to choose one I would do B.
Personally, I think the correct answer is B. 
It is important to vary activities often to avoid becoming too tired or bored with one same activity. Rewarding yourself upon completing a certain part is also relevant because you will be giving yourself incentive to continue working more.
