Declare not that you can hack and crack Mathematica is illegal. You have to of course pass all exams and fulfill the final requirements. However if you are asked to crack Mathematica software, either as an independent project or as part of the study, you will fail the course because of the illegal hack. Remember that hacking Mathematica can lead to you being expelled from your university, hence you could simply choose to stop studying at your present university.
It is always good to buy the software you use in the first place. If you are struggling to find a way that you can have access to Mathematica 11 at your present institution, explain to your lecturer or ask your peers in office that you need a license for Mathematica 11. At the very least you can use either one of the alternatives that I mention above. Also remember that all the advanced courses (i.e. the ones with you as the first or second author) are usually taught in your open source engine so it would be wise to invest some extra time and effort to get yourself included in these courses.
If you don't like Mathematica, do not learn it. Instead look at the alternatives, e.g. SAGE, which is an open source alternative to Mathematica. If you are still wedded to Mathematica, try giving dual processing to your machine and make sure your CPU has multiple cores, so that you can use Mathematica in parallel. If you are really grounded in mathematics and wish to try a new engine, you can carry out the research in SAGE or SageMath (which are based on SAGE).
Since learning of this topic, a number of mods have appeared with flagging it as an atrocious site, and they could quite well be right. It is a shame what most publishers have done because it is clear that Mathematica is an excellent and free program that should all schools have. Instead they are either monopolistic or not in tune with themselves. d2c66b5586
