Not exactly. It is always a good thing if you have your own personal laptop or computer while doing a BCA or MCA as these are very computer oriented fields. However, if you don't have your own personal computers, then many a times colleges have their own labs in which you can go freely and do your practice and exercises there. I won't say that it would be easy, but you can do the basic tasks for getting the degree in labs.

Hope I have answered your question. All the best!
