Question:
Do you have to learn in the sukkah? If it would be uncomfortable to do so, is there a heter to learn indoors?
Thank you
Answer:
Essentially the ideal place to learn on Sukkos is in the sukkah because the sukkah is the place we spend our time during sukkos, If however you are not comfortable learning there, and you will learn better somewhere else, you may do so.
Have a good Yom Tov
