Is there Any page or list or link, etc. where there are all the German verbs for A2/A1 exam?
You can find lists of words (in general, not only verbs) in some of the textbooks that are available for learning German at level A1/A2 by various publishing houses.
However, as these are not standardized down to the level of single words, these lists are valid especially for these textbooks or course programmes, and perhaps in other textbooks there might be minor difference (some words missing, others in use).
Please understand that the pedagogical concept behind such courses and textbooks is not the learn by heart a certain set of words. Rather, the idea is to lead learners into using the language (pro-) actively, and develop their competences. Competence means here: the ability to cope with unexpected situations and unfamiliar environments by using the tools (knowledge, skills) one actually has in a creative way.
In other words: you should not be concerned with word lists. You should be concerned with reading texts and understanding them, listening to people speaking, and understanding them; practicing speaking with people; practicing writing texts that are adequate in certain situations of everyday life.
What I would do is not learning words from a word list, but: reading the texts in the book; and if I see a word I do not understand, look it up. Then read the text again. And tomorrow again. Thus you will learn the word, but in context.
If you want to look up word lists anyway, please refer to the respective textbooks.
Here is one (of dozens):
Daniela Niebisch et al.: Schritte plus 1. Kursbuch und Arbeitsbuch. Niveau A1/1. Hueber, München 2009 (and following).
A word list is on pages 174-180. [I happen to have the 2016/10 edition]
There are various online offers with teaching materials for free. One is "Ich will Deutsch lernen" by the Association of German Community Colleges (Deutscher Volkshochschulverband).
Older plattform (content is good, graphics a bit outdated):
New plattform, opened in late 2018 (modern graphics, as for 2019 standards):
The Goethe Institute publishes word lists for the different language levels, e.g. the GOETHE-ZERTIFIKAT A2 WORTLISTE:
Unfortunately, it's not only verbs, but all vocabulary.
As far I know, there is no such list. Exams are created by German language teachers, and they know enough well, what is really needed for which level of knowledge.
As far I know, Japanese and Chinese school system has a list of their Kanjis what the students need to learn to pass it.
However, on the exam it is not a requirement to know all the verbs, there is a point limit (60% or 70%, as far I can remember) what you need to pass.
Find exams on the net. If you can fill them, here is the time to get also the paper. If not, search for questions about effective learning tips & tricks.
