Spanish language Q&A Forum

I use the app SpanishDict to help me check myself on certain concepts, especially on conjugations. For this concept, the gerund, the app uses past and present participles. Frankly, I did not receive a whole hell of a lot of instruction when it came to the difference between a participle and a gerund when I was younger but hey, I turned out ok! I have gotten the gist but the two things don't do the same thing  in Spanish as they do in English. I asked a Spanish professor friend of mine about this and he said one of them  (I can't remember which) was the gerund and the other is the participle. Is he correct? I got a questions wrong because I typed one form but it was actually the other. Also, is SpanishDict throwing me off?  

This goes against everything else I have learned or am learning in the classroom  - I cannot remember two sets of rules.  Any correct answer should be marked as correct, whether the so-called Latin American version or  Spanish version.   There doesn't need to be only 1 correct answer.

Are ´con tal de que´and ´a condición de que´ interchangeable ?

I agree with most of the replies here. The explanation seems very confusing.
