Extending Graduation/Suspending For 2 Years

Hi all,

Currently am a final year student studying Economics at Oxbridge/LSE. Essentially, my first year was during COVID and I ended up suspending and restarting my degree the next year. I then got somewhat mediocre first year results and got a summer in my second year that I did not convert. Now I have another summer in S&T/IBD at a mid BB coming up, but I am concerned that if I do not convert that I will graduate and be kind of screwed. Also want more time to try and get my grades up as currently quite behind, so am considering suspending and delaying graduation yet again for another year. 

My concern is how much it will impact my employability/ability to get masters/MBA degree if I have taken 5 years to complete my undergrad vs the usual 3. My transcript would not explicitly mention suspension but it would say Matriculation 2020 and then final exams being in 2024/25. Maybe I could claim I switched courses in first year and that I only took 4 years, also maybe there would be leniency due to covid? Also if I reapplied it would look kind of strange saying expected graduation 2026 for summers if I started in 2020?

Any feedback I could get on this would be much appreciated.
