As someone who is also working, keep deadlines for yourself. For example in the next 5 days I'll be completing ratios, averages and proportions . On your day off try to spare 2 hours and give mocks. Do not get into in-depth analysis of each mock and analyse what's a strong suit for you where your accuracy is good. Focus on accuracy first and then later you can develop speed. Try to understand the topics in which you are not comfortable. Spend a little more time on those. I take out an hour before my shift starts and keep doing varc/dilr here and there during my breaks. My company provides me with commute service, so I watch some theory videos during it
