Returning Mechanical BE(Hons) mid-3rd Student after 4 years break

Need some suggestions and advice from current Engineering students.

Quick background of me - I quit BE(hons) in middle of the 3rd year as I was studying part time (3 courses per sem) and working full time back in 2017-2020 and still manage to keep B+ average grades, later life got me and I decided to take a Semester break which turned into 4 year break. I have enrolled myself back to where I left off and decided to get over with leftover 11 courses.

So my question is should I take it slow this time and divide my 11 courses over 4 semester rather than doing them in 3 semesters? as it will only take 4 to 5 months more and I will have easy time grabbing the old stuff, I will be supporting myself mainly from my savings and will get some part time job if needed to as I am not sure how much help I will get from studylink with part time study.

Also how hard it will be to study wise since I have 4 and half year gap, I consider my self good student as I have A grades in all 3 math courses and never really struggled with study before, but now I am felling nervous and anxious about starting after long break. Is there any particular Software like Matlab, Inventor etc. that I should get myself familiar with before 2025 semester starts? I am currently working in a management job so there is no particular software used here which will help me directly with study.
