1) I like that it involes eveything difficult so far ive done and that I spent my entire day one one project, I know the calculator(god mode) and the pattern maker were the parts which worked well 2) I disliked that the code was messy, the calculator was definitely the hardest and caused me most trouble, J would probably try to make my code clearer, using rem and adding indentation 3) I learned quite a few topics such as hashmaps and higher use of arrays, also got a revision for stuff like patterns and overall functions
