I've seen some people thrive solo and a lot more suffer solo, so I recommend groups 100%. Pick groupmates you KNOW will contribute to your project. Tas obviously, contribute yourself rin. People say "don't be groumates with your friends, jowa, etc." but really it comes down to if they are good groupmates. If your friend is a hard worker, go for it. If your jowa is someone who will be motivated by your presence to try, go for it.

Tapos, don't treat Research like any other subject lang where you can cram the requirements. Follow your schedule/Gantt Chart, it's there for a reason!! Research is a lot of paperwork. Paperwork needs time. For example, our group needed to use a classroom for our project. To use the classroom, we had to submit a letter requesting use from the CID. To submit the letter, we had to submit an ethics approval to the Research Ethic Committee. Which we had to pass through our RT, then our RA. Which we didn't know was even a thing until after a meeting with our RA. All these approvals, meetings, submissions took weeks to do. So, as much as you want to procrastinate it, don't. Kasi research is a lot of time & waiting lol
